Question

what are the 3 parts of a nucleotide?
phosphate group, sugar and nitrogen base
phosphate group, sugar and nucleic acid
potassium group, sugar, and nitrogen base
phosphate group, guanine and nitrogen base

Explanation:

A nucleotide is composed of three main parts. The phosphate group is a key structural component. The sugar (deoxyribose in DNA or ribose in RNA) forms the backbone. The nitrogen - base (such as adenine, thymine, cytosine, guanine in DNA or adenine, uracil, cytosine, guanine in RNA) is responsible for the genetic code. Nucleic acid is a polymer of nucleotides, not a part of a single nucleotide. Potassium group is not a part of a nucleotide. Guanine is a type of nitrogen - base, not an additional separate part. So the correct answer is Phosphate Group, Sugar and Nitrogen Base.

Answer:

Phosphate Group, Sugar and Nitrogen Base
