NEET BIOLOGY

Detailed explanation-1: -The pentose sugar in DNA is called deoxyribose, and in RNA, the sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the 2’ carbon of the ribose and its absence on the 2’ carbon of the deoxyribose.

Detailed explanation-2: -Brief description of the pentose sugar There are two types of pentose sugar found in nucleic acid. These are ribose sugar and deoxyribose sugar. They have a five-membered ring in their structure.

Detailed explanation-3: -Ribose is a single-ring pentose [5-Carbon] sugar. The numbering of the carbon atoms runs clockwise, following organic chemistry rules.

Detailed explanation-4: -Complete answer: The pentose sugar found in nucleic acids has five carbon atoms. A nucleoside is the combination of a base and sugar. Ribose is the pentose sugar present in RNA, with one oxygen atom attached to each carbon atom.
