  1. Question 1

    Q1. A DNA segment requires a significantly higher temperature to denature compared to another segment. This indicates a higher concentration of which base pair?

    • A) Guanine and Cytosine
    • B) Adenine and Thymine
    • C) Adenine and Guanine
    • D) Cytosine and Thymine

    Answer: Guanine and Cytosine

    Explanation: G-C pairs have three hydrogen bonds, making them more stable and harder to denature than A-T pairs, which have two bonds.
