  • question_answer
    DNA fragments generated by the restriction endonucleases in a chemical reaction can be separated by             

    A)  centrifugation                                    

    B)  polymerase chain reaction                    

    C)  electrophoresis                  

    D)  restriction mapping                           

    Correct Answer: C

    Solution :

    DNA fragments generated by the restriction endonucleases in a chemical reaction    can    be    separated    by electrophoresis. The polymerase chain reaction is simply DNA replication in a test tube. Restriction mapping is the process of obtaining structural information on a piece of DNA by the use of restriction enzymes, e.g., endonucleases that recognise specific 4 to 8 base regions of DNA.
