2 DNA polynucleotide strands join together by hydrogen bonds between the bases.
each base can only join with one particular partner- this is called specific pairing.
Adenine always pairs with Thymine (A-T) and Guanine always pairs with Cytosine (G-C).
the two strands wind up to form the DNA double-helix.
the double-helix structure means DNA is very stable in the cell. :) x

∙ 11y agoWhen the cell enters metaphase and prepares to divide, the chromatin changes dramatically. First, all the chromatin strands make copies of themselves through the process of DNA replication. Then they are compressed to an even greater degree as they undergo a 10,000-fold compaction into specialized structures for reproduction, the chromosomes.

When DNA is coiled and folded and twisted into short condensed strands?
When DNA is twisted it is called a double helix and when DNA is coiled folded and twisted into short consended strands it is called alpha halix
What are sides of a double helix made of?
the sides of a double helix are composed of a chain alternating between a phosphate and a deoxyribose (5 carbon) sugar.
What is the major difference between normal DNA double helix and RNA double helix?
The term double helix refers to the structure formed by double-stranded molecules of nucleic acids. Only DNA forms a double helix because RNA is only single-stranded.
What is a double helix DNA or RNA?
Both DNA and RNA can exist in the double helix form, but only DNA is completely stable as a double helix. The double helix RNA is usually only short "hairpin" sections folding back on itself, never the long essentially linear form of double helix DNA.
Single helix is more stable as compared to the double helix?
like the computer single helix is 1g ram double helix like 2g ram so double helix more stable
What are the two strands of a double stranded chromosome called?
The double helix.
Which one is the smaller structure chromosome supercoil coil nuucleosome or double helix?
double helix
How can you tell the difference between the original and replicated part of each chromosome?
In late anaphase and G1 of interphase, a chromosome is unreplicated and consists of a single DNA double helix. A replicated chromosome contains two identical DNA double helices.
When DNA is coiled and folded and twisted into short condensed strands?
When DNA is twisted it is called a double helix and when DNA is coiled folded and twisted into short consended strands it is called alpha halix
what is the shape of a DNA?
double helix
How many DNA molecules are in a chromosomes?
There is one double helix DNA molecule per chromosome.
What are sides of a double helix made of?
the sides of a double helix are composed of a chain alternating between a phosphate and a deoxyribose (5 carbon) sugar.
What unwinds the parental double helix for DNA and whats is the relationship between genes and DNA?
The enzyme Helicase A gene is a small segment of DNA
How do helicases unwind a double helix?
Helicase uses free energy from ATP to break the hydrogen bonds between the double helix of the DNA. It breaks the bonds between adenine and thymine, and guanine and cytosine. This unzips the double helix structure.
What is the difference between single gene DNA and repetitive sequences of DNA?
DNA is double Helix But A Gene is a part of that double helix.
What is the shape of the DNA molecule known as?
Double Helix :D
What is the major difference between normal DNA double helix and RNA double helix?
The term double helix refers to the structure formed by double-stranded molecules of nucleic acids. Only DNA forms a double helix because RNA is only single-stranded.
