Question

What are the three parts of a nucleotide?

A. 5-carbon sugar, phosphate group, and nitrogenous base
B. 5-carbon sugar, phosphate group, and cabboxyl group
C. 5-carbon sugar, nitrogenous base, and adenosine

Answer 1

A. 5-carbon sugar, phosphate group, and nitrogenous base

Step-by-step explanation:

The three parts of a nucleotide are a 5-carbon sugar, a phosphate group, and a nitrogenous base. The 5-carbon sugar is typically either ribose or deoxyribose, the phosphate group is composed of one phosphate ion, and the nitrogenous base is either adenine, guanine, cytosine, or thymine.
