|
|
adenine
|
|
|
uracil
|
|
|
thymine
|
|
|
cytosine
|
Explanation:
Detailed explanation-1: -DNA and RNA share the nitrogenous bases A, G, and C. Thymine is usually only present in DNA and uracil is usually only present in RNA.
Detailed explanation-2: -DNA contains the bases cytosine, guanine, adenine, and thymine, whereas RNA contains cytosine, guanine, adenine, and uracil.
Detailed explanation-3: -Nucleotide The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T). In RNA, the base uracil (U) takes the place of thymine. DNA and RNA molecules are polymers made up of long chains of nucleotides.
