Detailed explanation-1: -The pentose sugar present in DNA is ribose .
Detailed explanation-2: -The pentose sugar is called deoxyribose in DNA because there’s a hydroxyl group that’s missing in deoxyribose that is present in ribose. You can see this indicated by the pink box. This is also why we call RNA ribonucleic acid and DNA deoxyribonucleic acid. Therefore, the pentose sugar found in DNA is deoxyribose.
Detailed explanation-3: -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-4: -deoxyribose, also called d-2-deoxyribose, five-carbon sugar component of DNA (q.v.; deoxyribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the DNA polymer and binds to nitrogenous bases.
Detailed explanation-5: -Ribose is a monosaccharide pentose sugar present in RNA while deoxyribose is a derived monosaccharide sugar present in DNA.
