The given diagram depicts the process of:
Correct answer: C. Polymerase chain reaction
- A. Gel electrophoresis
- B. DNA finger printing
- C. Polymerase chain reaction
- D. Recombinant DNA technology
Explanation
Polymerase Chain Reaction (PCR) is a method used to amplify DNA sequences, usually visualized with thermocyclers and reagents. As shown in figure, option C is correct. All other options don't involve DNA amplification. So A,B and D are wrong.
