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

Question

Quizplus · Accepted Answer

The description given matches the structure of RNA, which is a polymer made up of a five-carbon sugar (ribose), four different bases (adenine, uracil, guanine, and cytosine), and phosphoric acid. ATP and ADP are nucleotide molecules, not polymers, and proteins are made up of amino acids rather than the components listed in the question. DNA contains deoxyribose rather than ribose as its sugar component.
