What are the primary components of a nucleotide?
A
base, phosphate, and sugar
B
acid, base, and phosphate
C
base, oxygen, and phosphate
D
acid, chlorine, and hydrogen
Explanation: 

Detailed explanation-1: -A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. 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.

Detailed explanation-2: -Each nucleotide, in turn, is made up of a nitrogenous base, a pentose sugar, and a phosphate.
