Question

The correct statement regarding RNA and DNA, respectively is:

A

The sugar component in RNA is ribose and the sugar component in DNA is 2'-deoxyribose.

B

The sugar component in RNA is arabinose and the sugar component in DNA is ribose.

C

The sugar component in RNA is 2'-deoxyribose and the sugar component in DNA is arabinose.

D

The sugar component in RNA is arabinose and the sugar component in DNA is 2'-deoxyribose.

Step-by-Step Solution

Nucleic acids are composed of nucleotide monomers, which consist of a nitrogenous base, a pentose sugar, and a phosphate group. As the names suggest, the sugar found in RNA (Ribonucleic acid) is a pentose sugar called ribose, while the sugar found in DNA (Deoxyribonucleic acid) is 2'-deoxyribose . The difference between them is the presence of an -OH group at the 2' carbon in ribose, which is replaced by just an -H atom in 2'-deoxyribose.

Exam Context & Concepts Covered

This question aligns with the NEET CHEMISTRY syllabus, specifically targeting concepts from Biomolecules.
