What are the three parts of a nucleotide? an organic base, a protein, and a sugar an organic base, a phosphate group, and water an organic base, a phosphate group, and a sugar an organic base, an amino acid, and water

an organic base, a phosphate group, and a sugar

Explanation:

A nucleotide is made up of 3 parts. We know a nucleotide is not made up of water so we are left with 2 choices. Nucleotides are made up of phosphate group, 5-carbon sugar, and nitrogenous base. The nitrogeneous base is typically adenine. The answer choice that matches this the closest is an organic base, a phosphate group, and a sugar.

The organic base is the nitrogeneous base and the sugar is the 5-carbon sugar.
