Question

Quizplus · Accepted Answer

A deoxyribose nucleotide consists of a deoxyribose sugar, a nitrogenous base, and a phosphate. Therefore, the correct answer is C, which includes all three components. Choice A only includes the sugar and base, while choice B only includes the sugar and phosphate, and choice D includes a different sugar (ribose) than the one found in DNA. Choice E describes the structure of a nucleotide, but doesn't specify the type of sugar present.
