DNA is a polynucleotide, made up of nucleotides. It has a phosphate-sugar backbone. (The sugar is deoxyribose). And, 'internal' are nitrogenous bases that are strung together (by hydrogen bonds) to complementary nitrogenous bases forming something like the rungs of a ladder. The DNA molecule is wound into a double helix.
There are 4 types of the bases, adenine, cytosine, guanine and thymine, abbreviated A, C, G and T.
A triplet of bases 'codes' for a single amino acid. Thus a whole string of triplets codes for a sequence of amino acids, a polypeptide. A gene is defined as the code for a single polypeptide.
Thus, these bases have a lot to do with DNA.
The nitrogenous bases in DNA are......AdenineCytosineGuanineThymine
DNA polymerase matches the bases on the parent strand.
There are 4 bases in DNA: adenine, thymine, cytosine, and guanine.
TACA
The mRNA bases are complementary to the DNA bases, and so form H-bonds when the DNA is single-stranded. DNA - mRNA A - U T - A C - G G - C
Describe how each of the DNA nitrogen bases pair together
There are four types of bases in DNA: adenine, cytosine, guanine, and thymine. However, a molecule of DNA may be a polymer of millions of these bases in a specific arrangment.
The four DNA bases are: Adenine Thymine Cytosine Guanine
The nitrogenous bases of DNA are:- Adenine (A) Guanine (G) Thymine (T) Cytosine (C)
The bases are ripped apart by helicase.
The four nitrogenous bases in in DNA are adenine, thymine, cytosine, and guanine.
There are four bases in a DNA "ladder"... It is called a ladder because of the "two sides" and the bases... In DNA replication, they obviously replicate and the two sides are replicated as are the bases. (A,T,C,G)
