∙ 15y agoA bacterial plasmid is usually a circular (sometimes linear) piece of double-stranded DNA found in bacteria that is distinct from the bacterium's chromosome. It carries non-essential genes that can augment a bacterium's ability to survive in certain circumstances. For example, some plasmid carry genes that enable a bacterium to metabolize a certain type of nutrient it otherwise can't, other plasmids carry genes that enable a bacterium to conjugate (transfer DNA to another bacterium), and still other plasmids carry genes that confer antibiotic resistance. Due to the small size and versatility of plasmids and the ease of operating with bacteria, plasmids have become a central part of research and biotechnology where plasmids are used for a vast variety of experiment from expressing human genes in bacterial cells to DNA sequencing.

These small rings of DNA sometimes contain genes that confer special characteristics to bacteria. Antibiotic resistance being an example.

What is a promiscuous plasmids?
plasmids that have transfer systems that allow transfer of DNA to unrelated species are called promiscuous plasmids.
What are the 2 types of DNA plasmids found in microorganisms?
Plasmids are autonomous DNA molecules of varying size which are localized within the cytoplasm of bacteria. There are two kinds:virulence plasmids = determines the virulence factors of the bacteriaresistance plasmids (R-plasmids) = determines the bacteria's resistance to anti-infective agents
What types of plasmids allows a bacterial cell to kill its competitors?
Bacteriocin Plasmids
What is inside the bacterium below is a small circular piece of DNA called?
Chromosomes unlike our cell they roam freely in the cytoplasm
Do mitochondria have plasmids?
No. Plasmids are used for cell replication, and cannot be a fraction of something that a fraction of a cell.
What causes protozoan plasmids?
Protozoa do not have plasmids in nature.
What is a promiscuous plasmids?
plasmids that have transfer systems that allow transfer of DNA to unrelated species are called promiscuous plasmids.
In many bacteria genes that confer resistance to antibiotics are carried on what dissimilation plasmids exons plasmids factors or transposons?
plasmids

Is prokaryote used in plasmids?
No, it's vise versa. Plasmids are used in and by the prokaryotes.
What types of plasmids allows a bacterial cell to kill its competitors?
Bacteriocin Plasmids
Plasmids are unique to what?
Plasmids are small segments of genetic material which are passed from one bacteria to another, so plasmids are unique to bacteria, which may also be referred to as prokaryotes.

No. Plasmids are used for cell replication, and cannot be a fraction of something that a fraction of a cell.
Small accessory chromosomes found in bacteria and useful in recombinant DNA procedures are called?
plasmids.
Are plasmids found in plant or animal cells or both?
plasmids are found in plant cells only
Do all eukaryotic cells have plasmids?
Most plasmids are found in prokaryotic cells, but a few eukaryotic cells also have plasmids. An example of a eukaryote with plasmids is the unicellular yeast Saccharomyces cerevisiae.
