Question

uracil guanine cytosine thymine which nitrogenous base is not found in dna?

Explanation:

DNA (Deoxyribonucleic acid) contains four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G). RNA (Ribonucleic acid) contains uracil (U) instead of thymine. Since the question asks which nitrogenous base is NOT found in DNA, we check the list of DNA bases. Uracil is an RNA - specific base.

Answer:

Uracil
