  1. Question 1

    Q1. When comparing Ribose and Deoxyribose sugars in a structural diagram, which carbon atom lacks an oxygen atom in the Deoxyribose sugar?

    • A) C1
    • B) C2
    • C) C3
    • D) C5

    Answer: C2

    Explanation: Deoxyribose lacks an oxygen atom specifically at the C2 position; C3 is tempting as it also bears a hydroxyl group in ribose.
