Canvas Classes · Accepted Answer

Nucleic acids contain pentose sugars as a fundamental building block.
- In DNA (Deoxyribonucleic Acid), the sugar moiety is -D-2-deoxyribose, which lacks a hydroxyl (OH) group at the 2' carbon position.
- In RNA (Ribonucleic Acid), the sugar moiety is -D-ribose, which retains its 2'-OH group.

Hence, the sugars are -D-2-deoxyribose and -D-ribose respectively.
