What is the lytic cycle?
The lytic cycle is one of two methods of viral reproduction, theother being the lysogenic cycle. These cycles should not, however,be seen as separate, but rather as somewhat interchangeable. Thelytic cycle is typically considered the main method of viralreplication (reproduction), since it results in the destruction ofthe infected cell. The lytic cycle is often described in steps, sometimes three steps,sometimes five steps or six steps. But all describe the sameprocess. See the related question below for more information aboutthe steps of the lytic cycle. Penetration To infect a cell, a virus must firstenter the cell through the plasma membrane and (if present) thecell wall. Viruses do so by either attaching to a receptor on thecell's surface or by simple mechanical force. The virus thenreleases its genetic material (either single- or double-strandedDNA or RNA) into the cell. In doing, the cell is infected and canalso be targeted by the immune system. Biosynthesis The virus' nucleic acid uses the hostcell's machinery to make large amounts of viral components. In thecase of DNA viruses, the DNA transcribes itself into messenger RNA(mRNA) molecules that are then used to direct the cell's ribosomes.One of the first polypeptides to be translated is one that destroysthe hosts' DNA. In retroviruses (which inject an RNA strand), aunique enzyme called reverse transcriptase transcribes the viralRNA into DNA, which is then transcribed again into mRNA. Maturation and lysis After many copies of viralcomponents are made, they are assembled into complete viruses. Thephage then directs production of an enzyme that breaks down thebacteria cell wall and allows fluid to enter. The cell eventuallybecomes filled with viruses (typically 100-200) and liquid, andbursts, or lyses; thus giving the lytic cycle its name. The newviruses are then free to infect other cells. Lytic cycle without lysis Some viruses escape thehost cell without bursting the cell membrane, but rather bud offfrom it by taking a portion of the membrane with them. Because itotherwise is characteristic of the lytic cycle in other steps, itstill belongs to this category. Hepatitis C viruses presumably usethis method.
What is the difference between the lytic cycle and the lysogenic cycle?
Lysogenic cycle is a viral replication cycle in which thevirus's nucleic acid is integrated into the host cell's chromosome,a pro-virus is formed and replicated each time the host cellreproduces, the host cell is not killed until the cycle isactivated. At this time the virus remains quiet for a very longtime and it is said to be hidden. Lytic cycle is a viral replication cycle in which a virustakes over a host cell's genetic material and uses the host cell'sstructures and energy to replicate until the host cell bursts,killing it. This cycle kills the host cell almost right away. Simplified answer: The lytic cycle kills the host and lysogenykeeps the host alive.
Which is more efficient the lytic cycle or the lysogenic cycle?
Lytic Cycle is more efficient, for each lyse of the host cell takes approximately 18 hours. In contrast, the lysogenic cycle can take many years. EX: HIV/AIDS
What type of viruses use the lytic cycle?
The lytic cycle causes destruction of infected cells and theirmembrane. A virus that uses a lytic cycle reproduces itself ormakes copies that are sent back into the environment and they arecalled virulent viruses.
List the five phases of the lytic cycle?
The lytic cycle is one of the cycles of viral reproduction. Thephases of the lyric cycle are penetration, biosynthesis, generegulation biochemistry, maturation and lysis. In some cases thelysis phase is replaced by the productive phase.
What is the lytic cycle of virus reproduction?
The lytic cycle and the lysogenic cycle are the two life cycles of viruses. The lytic cycle is typically considered the main method of viral replication, since it results in the destruction of the infected cell. a it the virus injects its own nucleic acids into a host cell b the viral acids form a circle in the center of the cell c the cell then mistakenly copies the viral acids instead of its own nucleic acids d then the viral DNA organize themselves as viruses inside the cell e when the number of viruses inside becomes too much for the cell to hold, the membrane splits and the viruses are free to infect other cells 1 Penetration - 2 Biosynthesis - 3 Gene regulation biochemistry 4 Maturation and lysis
Is dengue fever lytic or lysogenic cycle?
Dengue fever is a lysogenic cycle because it does not lyse the hostcell. Dengue fever is a topical disease that is mosquito-borne.
Distinguish between lytic and lysogenic cycle?
lytic cycle . host bacterium undergoes lysis...i.e it is destroyed . progeny phage are produced . it cannot be converted into lysogenic cycle . lysogenic . host bacterium is not affected .there is a symbiotic relationship between the bacterium and the phage . DNA of the phage becomes part of the bacterial chromosome. . No progeny particles produced . it can be converted into lytic cycle by exposure to certain chemical and physical agents like UV rays,hydrogen peroxide and nitrogen mustard

Does monkey pox go through lytic cycle?
The monkeypox virus does go through a lytic cycle in order toreplicate. This virus is a zoonotic disease that can affect bothanimals and humans.
The correct sequence of steps in the M phase of the cell cycle is?
The correct sequence of steps in the M phase of the cell cyclestarts with Prophase. From there the cell goes through prometaphse,metaphase, anaphase, telophase, and finally cytokinesis.
What is the correct order of the cell cycle?
Most of the cell's life is spent in interphase. The cell increasesin size, then replicates its DNA. After some additional growth, thecell is ready to divide. Mitotic division occurs and the twodaughter cells each return to interphase. Some cells entersenescence and cease to divide.
What is the correct order of water cycle?
Evaporation, Transpiration, Condensation , Precipitation Absorptionl, Infiltration, Ground water, and then runoff Those are the steps of the water cycle! made by Trey Cuellar
How lytic cycle is more efficient?
The only thing the lytic cycle is more efficient in is killing the cell. The lytic cycle is when the initiation of making lots of bacteria copies begin. Once complete, the cell bursts and the virus products will scatter and infect other cells.

The Sequence events of the cell cycle is . interphase . prophase . metaphase . anaphase . telophase.
A lytic cycle concludes with what?
the lytic cycle concludes with the host cell being burst open releasing more viruses which then repeats the lytic cycle
What are the steps of the lytic cycle?
The lytic cycle is one of the two cycles of viral reproduction, the other being the lysogenic cycle. These cycles should not, however, be seen as separate, but rather as somewhat interchangeable. The lytic cycle is typically considered the main method of viral replication, and it results in the immediate destruction of the infected cell. A generalized scheme is presented here. There are variations in the process depending on the type of virus (its genome) and the type of host (bacteria or plant cells or animal cells). The six steps of the lytic cycle operative in viral pathogenesis can be summarized as follows: . The virus finds a host cell/ Contact (or initial infection): Viruses require a host to replicate. To infect a cell, the virion links on to a specific region (like a receptor or a glycoprotein) on the surface of the host cell. Viruses do so by either attaching to a receptor on the cell's surface or by simple mechanical force. . The virus enters the cell/ Injection (or in some cases the virus' genes are injected into the cell while the virion remains outside the cell): Once a virus attaches, it enters the cell through the plasma membrane and (if present) the cell wall. The virus then releases its genetic material (either single- or double-stranded DNA or RNA) into the cell. In doing this, the cell is infected and can also be targeted by the immune system. . The virus takes over the host cell/Integration: The viral genetic material integrates with the host genetic material and uses it to express viral genes instead of the usual cell function. In other words, the virus hijacks the gene expression machinery of the host. Technically, the virus' nucleic acid uses the host cell's machinery to make large amounts of viral components. In the case of DNA viruses, the DNA transcribes itself into messenger RNA (mRNA) molecules that are then used to direct the cell's ribosomes. One of the first polypeptides to be translated is one that destroys the host cell's DNA. In retroviruses (which inject an RNA strand), a unique enzyme called reverse transcriptase transcribes the viral RNA into DNA, which is then transcribed again into mRNA. . Biosynthesis/ Viral gene expression: Viral genes are expressed and parts (building blocks) of new virions are formed. After many copies of viral components are made, they are ready to be assembled into complete virus particles. . The genes from the virus turn the cell into a virus factory/ Packaging and maturation: Copies of the viral genetic material are packaged into the newly formed virions and the parts are assembled to form many new complete virus particles. . The new viruses break out and find a new host to repeat the process/ Lysis and infection: Once new complete virions are fully formed, the production of an enzyme that breaks down the cell wall and allows fluid to enter is begun. The cell eventually becomes filled with typically 100-200 virions and liquid. It then bursts open, which is called host cell lysis. This is how the lytic cycle got its name. Once the host cell is lysed, a huge number of new viruses are released into the inter cellular spaces of the host. The new viruses are then free to attach to and infect other cells in the same host, or to shed from the first host and infect others. This process repeats cell by cell and host by host. Note about a "Lytic" cycle without lysis: Some viruses escape the host cell without bursting the cell membrane. Instead, they bud off from it by taking a portion of the membrane with them to package the new virion. Eventually the host cell's membrane can be totally used up in the budding process, so it is ultimately destroyed by this other mechanism, just as host cells that are destroyed by lysis. Hepatitis C viruses presumably use this method.
Which viruses follow the lytic cycle?
One group of viruses that follow the lytic cycle is the T-even Bacteriophage group. Their host is E.coli.
What is the correct order of the passage of oxygen during the first phase of the respiration cycle?
There are three phases of respiration. The first phase is calledpulmonary ventilation. The correct order of the passage of oxygenduring the first phase is inhalation of air into the alveoli or airsacs in the lungs and exhalation of the air. Oxygen diffuses fromthe alveoli into the blood then the oxygen diffuses from the bloodto the cell.
What is the lytic cycle for plant virus?
Viruses must enter through wounds or be assisted by other plant parasites, including nematodes, fungi, and, most often, insects that suck the plant's sap. Once one plant is infected, it can spread infection to other plants in its pollen and seeds.
What part of the lysogenic cycle is like the lytic cycle?
The Phage or virus attaches to the cell and penetrates it, like the lytic cycle. However it doesn't kill the cell immediately, it will only destroy it after numerous chromosomal replications.
Does the Norwalk virus have a Lytic or Lysogenic cycle?
The Norwalk virus (Norovirus) does not have a lyosgenic cycle. It does not remain dormant as lysogenic viruses can. It is lytic and is considered virulent as many lytic viruses are. Most bacteriophages are lysogenic. See link below:

I had this on an online Advance Placement Biology activity, the answer for this question on my activity was Viral DNA is incorporated into host chromosomes.
What is the difference between lytic cycle and a lysogenic cycle?
The lysogenic cycle incorporates its DNA into the cells DNA, lets the cell resume normal growth by reproduction, so that all the cells have viral DNA and lyse to produce more viruses than ever. The lyctic cycle merely infects and lyses one cell at a time.
Do viruses undergo the lytic and lysogenic cycle?
Yes, viruses do undergo the lytic and lysogenic cycle. Depending on what type of virus determines which process they undergo.
What are the phases of menstrual cycle in order?
menstrual phase (menstruation) . proliferative phase . ischemic phase . follicular phase . ovulatory phase (ovulation) . luteal phase (also known as secretory phase)
What happens at the end of the lytic cycle?
The host cell bursts to release the newly formed virus particles and then it dies.
What happens to the cell after the lytic cycle?
Once the virus is inside the cell it's either is lytic or lysogenic. If the virus is lysogenic then it eventually turns to lytic and destroys the cell releasing a lot of baby viruses.
What is one way that the lytic and lysogenic cycles are different?
In the lytic cycle, the virus lyses, or destroys the host cell after the virus has reproduced using the host cell's machinery. In the lysogenic cycle, this does not happen. A virus in the lysogenic cycle can, however, enter the lytic cycle.
What is the correct order of the life cycle of mosses?
well...1st he was born but then his mum put him in a bascket into the nile so he wouldn't get caught then he grew up to be an Egyptian then he was a Shepard then he went back to Egypt then he did the 10 curses then he died when he was 120 somthing! ;D

Put the phases of the business cycle in the correct order 1-4 in which they follow after a boom?
To put these phrases in order a person will need to know what thephrases are. Since they are not provided the answer can not beknown.
What effect will a virus in the lytic cycle have on an organism?
It is in the "reproduction" process when in the lytic cycle, so theeffect will be that the virus will force the organism to replicatemore and more "baby" viruses. The host cells will eventually die orbe killed when it splits open (or buds) to release the new virusparticles. The new particles will infect more and more cells of thehost, killing the host's cells each time they split, making thehost feel sicker and sicker until their defense systems figure outhow to kill the viruses. The Norwalk virus (Norovirus) does not have a lyosgenic cycle. Itdoes not remain dormant as lysogenic viruses can. It is lytic andis considered virulent.
How are lysogenic and lytic cycles different?
the lytic cycle causes disease apex 2.1.6 During the iysogenic cycle, the cell is not killed
Why is the lytic cycle called the lytic cycle?
Lytic refers to lysis which means separate in Greek. When a virus has replicated in a cell, the new viruses made in the cell cause the cell to separate or split open so the virus particles can get out and infect more cells and make more viruses.
What is the correct order of phases of the moon?
New moon, first quarter, full moon, last quarter, new moon. The days between new moon and first quarter are called offhandedly "crescent" moons, as are the days between last quarter and new moon. The days between first quarter and full, and full and last quarter are called "gibbous moon".
How are the lysogenic and lytic cycles diffrent?
Phages have lytic or lysogenic cycle to reproduce themself.Phages that have lytic life cycle it kill bacteria after new progenicy of phages are relaset from host bacteria.Phages with lysogenic cyclel it integrate their DNA to the host bacteria.However, when bacteria that carry genetic material of lysogenic phages are posed to stress can switch to the lytitic cycle to produce a new progeny of pahages.
What might cause a virus to suddenly enter the lytic cycle?
stress to the host cell novanet is a scam. so is gradpoint. all scam 100% fake and stolenfrom this website
Why is a virus's reproduction cycle called the lytic cycle?
Lysis means cut open or split, the word lytic comes from lysis. In the lytic cycle, the host cells that have been infected by a virus will fill up with new viruses until they gets too full and then they split open to release the new viral particles, and the cell dies. See more about the lytic cycle in the related questions below.
How does the lytic cycle show that viruses are not living things?
The lytic cycle involves the viruses injecting nucleic acid intothe cell to make the cell "sick". The lytic cycle proves virusesare non-living because the only way the cells reproduced at the endof the cycle was because of the host cell. A virus cannot reproduceon its own (only can with a host cell) as to which any living thingcould. Viruses are non-living organisms and the lytic cylce provesjust that. Viruses alos contain protogramo fluids that kill thecell. These fluids are what mostly make a virus considerednon-living for reasons scientists have not yet come to anunderstanding to. Hope this helped you!:)
What is the proper order of phases of the cell cycle?
G1 phase then S phase then G2 phase then comes meitosis (interphase, prophase, metaphase, anaphase, telophase) then cytokinesis
Which of these best describes a cycle of lunar phases in the correct order?
This is astonishing! You're looking at a list, and you can't decide which item on the list is the correct one, but you expect me to pick the correct one without even seeing the list. Any cycle that includes these phrases in this order is correct: . New Moon . Waxing crescent . First Quarter . Waxing gibbous . Full Moon . Waning gibbous . Third quarter . Waning crescent
How are lytic and lysogenic cycles the same?
They are the same only in the way that take over the cell hosts. The lytic cycle will cause the cell to rapidly rupture and die at the end of their life cycle. The lysogenic virus will hide in the cell's nucleus for many cycles until it too will cause the death of the cell.
How long does the lytic cycle usually take?
This will vary according to the type of virus and according to the host cells.
