Dna, rna, and starch: what do these three important biomolecules have in common? a) they all contain at least one carboxyl group. b) the presence of at least one carbon-based sugar. c) the presence of strong hydrogen bonds between monomers. d) they all contain at least one amino group composed of a nitrogen atom. submit

The correct answer is -

B)The presence of at least one carbon-based sugar.

Explanation:

RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) are the two types of nucleic acids that are composed of nucleotide (monomer of nucleic acid).

A nucleotide has three parts, which are pentose sugar (5 carbon sugar), nitrogenous base, and phosphate group.

Starch is a complex carbohydrate as it is composed of several units of simple sugar such as glucose.

Thus, the presence of at least one carbon-based sugar is common in DNA, RNA, and Starch.
