  1. Which one of the following represents a palindromic sequence in DNA?








  1. View Hint View Answer Discuss in Forum

    A palindromic sequence is a nucleic acid sequence (DNA or RNA) that is the same whether read 5' (five-prime) to 3' (three prime) on one strand or 5' to 3' on the complementary strand with which it forms a double helix.
    5' - GAATTC - 3'
    3' - CTTAAG - 5'
    It is a palindromic sequence of DNA cut by restriction enzyme Eco RI.

    Correct Option: A

  1. There is a restriction endonuclease called EcoRI. What does “co” part in it stand for?








  1. View Hint View Answer Discuss in Forum

    EcoRI is an endonuclease enzyme isolated from strains of E.coli and a part of restriction modified system. So co part stands for coli.

    Correct Option: D

    EcoRI is an endonuclease enzyme isolated from strains of E.coli and a part of restriction modified system. So co part stands for coli.
