What term describes the five-carbon sugar component of nucleotides?

Explanation:
Nucleotides are built from three parts: a sugar, a phosphate group, and a nitrogenous base. The five-carbon sugar component is a pentose, which in DNA is deoxyribose and in RNA is ribose. Among the given terms, naming the sugar as a five-carbon sugar directly identifies this component of the nucleotide. The other options refer to different parts or concepts: the nitrogen base is the base partner, codons are triplets of bases in mRNA, and tRNA is a separate molecule involved in translation. So describing the sugar as a five-carbon sugar correctly identifies the sugar portion that links to the phosphate and base to form the nucleotide backbone.
