    If one strand of DNA has the sequence ATGCTTGA, the sequence in the complementary stand would be

    A)  TACGAACT   

    B)  TCCGAACT

    C)  TACGTACT    

    D)  TACGTAGT

    Correct Answer: A

    Solution :

    : The two strands of DNA are complimentary to each other in the sense that the sequence of bases in one strand automatically fixes the sequence of bases in the other strand. Adenine [A] pairs with thymine [T] by two hydrogen bonds while guanine [G] pairs with cytosine [C] with three hydrogen bonds.
