When comparing the ribose sugar in RNA to the deoxyribose in DNA, which specific change occurs at the carbon-2 position during the transition to deoxyribose?
Q1. When comparing the ribose sugar in RNA to the deoxyribose in DNA, which specific change occurs at the carbon-2 position during the transition to deoxyribose?
Answer: Removal of oxygen
Explanation: Deoxyribose lacks the oxygen atom at the C-2 position found in ribose. Adding oxygen would make it ribose, not deoxyribose.
