Question

Quizplus · Accepted Answer

A nucleotide is composed of three parts: a nitrogenous base, a sugar (either ribose or deoxyribose), and a phosphate group. This basic structure forms the building blocks of DNA and RNA molecules. Uracil is a nitrogenous base found only in RNA molecules. Nucleotides do not directly code for amino acids, but sequences of nucleotides (called codons) do code for specific amino acids in the process of protein synthesis.
