    If the sequence of one strand of DNA is written as follows:

    5‘-ATGCATGCATGCATGCATGCATGCATGC-3‘

    Write down the sequence of complementary strand in 5‘→3‘ direction
    Ans : The DNA strands are complementary to each other with respect to base sequence. Hence, if the sequence of one strand of DNA is

    5‘- ATGCATGCATGCATGCATGCATGCATGC - 3’

    Then, the sequence of complementary strand in direction will be

    3‘- TACGTACGTACGTACGTACGTACGTACG - 5’

    Therefore, the sequence of nucleotides on DNA polypeptide in direction is

    5‘- GCATGCATGCATGCATGCATGCATGCAT- 3’
