Which description correctly identifies a nucleotide? A nucleotide consists of a five carbon sugar bonded to a phosphate. A nucleotide has three main parts: a phosphate, a sugar, and a nitrogenous base. Nucleotides are formed by a dehydration reaction between two or more nucleic acids. A nucleotide consists of billions of DNA monomers that are condensed using histone proteins.
