    Identify from the following which can give a complementary and palindromic sequence.

    A)  5ATATCC3   

    B)  5 CCGAAT 3

    C)  5GAATTCS   

    D)  3AGGTTCS

    Correct Answer: C

    Solution :

    Palindromes are the sequences in which nitrogen bases read the same both forward and backward direction. So, 5 GAATTC 3 is the palindromic sequence. These palindromes in mRNA cause formation of hair pins which cause RNA polymerase to slow down or cause a pause in transcription.
