    32percent

    Explanation:

    Chargaff rule states that a DNA has this base pair arrangements

    Adenine-Thymine

    Cytosine-Guanine

    The base pairs also contain almost equal amount of substance in them.

    This means Thymine which has 18percent also has 18percent Adenine in the base pair

    The remaining percentage will be calculated by 100-18+18=100-36=64

    Cytosine and Guanine will share the remaining the 64% which translates to 32% for each of them.

    Cytosine-32% and Guanine=32%
