Question

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

Answer 1

The correct option is B A-Restriction endonuclease, B-Restriction endonuclease, C-DNA ligase, D-Transformation

At A and B , there is a work of same restriction endonuclease enzyme cutting both foreign DNA and vector DNA at specific point.

At C, ligases join foreign DNA to plasmid .

At D, there is a process of transformation occur.

So, the correct option is 'Option B' .
