Question

The three components of a nucleotide are ______, ______ and ______.

Answer 1

The three components of a nucleotide are a phosphate group, a pentose sugar and a nitrogenous base.

Explanation:

The pentose sugar (either ribose in RNA or deoxyribose in DNA) binds to a phosphate group to form the continuous backbone of the nucleic acid chain. Attached to this sugar is a nitrogenous base, which can be adenine, thymine, cytosine, guanine, or uracil. Together, these three parts form the basic building blocks that link up to store and encode genetic information.
