The four nitrogenous bases of DNA are
A
Adenine, guanine, cytosine, and uracil
B
Adenine, guanine, cytosine, and thymine
C
Adenine, guanine, ribose and deoxyribose
D
Adenine, deoxyribose, cytosine, and uracil
Explanation: 

Detailed explanation-1: -There are four nucleotides, or bases, in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). These bases form specific pairs (A with T, and G with C).

Detailed explanation-2: -Answer and Explanation: The correct answer is (b): uracil. DNA contains four bases which are adenine, guanine, thymine, and cytosine. Uracil is the nucleotide that is found in RNA instead of thymine.

Detailed explanation-3: -Thus, the four nitrogenous bases in the DNA are adenine, guanine, cytosine and thymine.
