Quizplus · Accepted Answer

A nucleoside is formed by a nitrogenous base (adenine, guanine, cytosine, thymine, or uracil) and a sugar (ribose or deoxyribose). The base and sugar are connected by a glycosidic bond. Therefore, option A (base + sugar) correctly represents the composition of a nucleoside. Option B (base + phosphate) represents a nucleotide, while option C (base + phosphate + sugar) and option D (phosphate + sugar) represent different parts of a nucleotide.
