Question

Which of the following macromolecules is considered a homopolymer?
A)polypeptides
B)ribonucleic acids
C)deoxyribonucleic acids
D)starch
E)all of the above

Accepted Answer

Starch is considered a homopolymer because it is made up of repeating units of glucose molecules. Polypeptides, ribonucleic acids (RNA), and deoxyribonucleic acids (DNA) are all considered heteropolymers because they are made up of different types of monomers (amino acids for polypeptides, nucleotides for RNA and DNA).
