Question

Quizplus · Accepted Answer

A nucleotide consists of a nitrogenous base, a five-carbon sugar (ribose or deoxyribose), and a phosphate group. The nitrogenous base can be either a purine (adenine or guanine) or pyrimidine (cytosine, thymine or uracil) ring. The sugar and the base are joined together by a covalent bond known as a glycosidic bond. The sugar and the phosphate are joined by another covalent bond called a phosphodiester bond. Together, these three components form the basic structure of a nucleotide.
