Identify the carbon atom numbered from C ₁ ^ to C ₅ ^ of monosaccharide unit of DNA nucleotide that lacks oxygen atom from -OH group.

Step-by-step solution

The monosaccharide unit in DNA is deoxyribose, a pentose sugar distinguished from ribose by the absence of oxygen at the C-2′ position. Ribose contains a hydroxyl group (-OH) at C-2′, whereas deoxyribose substitutes this with a hydrogen atom (-H). All other carbon atoms (C-1′, C-3′, C-4′, C-5′) either include oxygen in hydroxyl groups, the furanose ring, or participate in glycosidic or phosphodiester bonds. B
