    The flow chart given below represents the process of recombinant DNA technology. Identify A, B,C and D.

    A) A-Restriction endonuclease, B-Restriction exonuclease, C- DNA ligase, D- Transformation

    B) A-Restriction endonuclease, B-Restriction endonuclease, C-DNA ligase, D-Transformation

    C) A-Restriction endonuclease, B-Restriction endonuclease, C-Hydrolase, D-Transformation

    D) A-Restriction endonuclease, B-Restriction endonuclease, C-Hydrolase, D-Transduction

    Correct Answer: B

    Solution :

    [b] A and B are restriction endonuclease because same restriction enzyme cuts both foreign DNA and vector DNA at specific point. C is DNA ligase which joins foreign DNA to vector DNA. The newly formed recombinant DNA is transformed in bacteria and the bacterial cells are allowed to divide.
