Which polymer is a copolymer of a five-carbon sugar, four different bases (adenine, thymine, guanine, and cytosine), and phosphoric acid?
A) ATP
B) ADP
C) Kevlar
D) DNA
E) RNA

Question

Quizplus · Accepted Answer

The polymer described is DNA, which is composed of a five-carbon sugar (deoxyribose), four different bases (adenine, thymine, guanine, and cytosine), and phosphoric acid. ATP and ADP are nucleotides involved in energy metabolism, but they do not contain all of the components listed. Kevlar is a synthetic polymer used in bulletproof vests and does not contain any of the listed components. RNA is a polymer similar to DNA, but it contains a different sugar (ribose) and the base uracil instead of thymine.
