    A segment of DNA has 120 adenine and cytosine bases. The total number of nucleotides present in the segment is

    A)  60                                         

    B)  240

    C)  120                       

    D)         480

    Correct Answer: D

    Solution :

    From Chargaff?s rules, the amount of adenine is always equal to that of thymine, and the amount of guanine is always equal to that of cytosine. \[A=T(120)\] \[G=C\,(120)\] The total number of nucleotides would be \[120\times 4=480.\]
