Deoxyribose sugars have ______ at _____ carbon.

Explanation:
Deoxyribose differs from ribose by missing the hydroxyl group at the 2' position. In DNA, the 2' carbon carries only a hydrogen, not an OH, hence the name 2'-deoxyribose. This absence at 2' is what keeps DNA chemically more stable than RNA. The 3' carbon, where a hydroxyl group remains, is the point that forms the phosphodiester bond during DNA backbone formation, enabling chain growth from the 5' end to the 3' end. So the correct statement is hydrogen at the 2' carbon.
