"Bases" when speaking of DNA refers to the nitrogen bases. There are four: adenine, guanine, cytosine, and thymine. They comprise the "rungs" of the DNA ladder and are hydrogen-bonded.
RNA has the base uracil which replaces the thymine base of DNA.
RNA has the base uracil which replaces the thymine base of DNA.
TACA
Exocytozine
Thymine
So essentially the difference is that in DNA-DNA base pairs thymine bonds with adenine while in DNA-RNA base pairs thymine bonds to uracil.
The nitrogen base thymine in DNA is replaced by the nitrogen base uracil in RNA.
DNA is deoxyribonucleic acid why DNA is called acid but it contains nitrogenous base.
It is not a DNA base pair itself, it is a DNA nucleotide base. It does however, form a base pair when bonded with adenine.
DNA
Yes its a base in the DNA.
The base pairs found in DNA are adenine with thymine, and cytosine with guanine.
