NEET Zoology Recombinant DNA MCQ Question

Type: MCQ-conceptual-Hard-Class 12

Which combination of statements accurately describes the process of creating recombinant DNA?

A
  1. Plasmids can be used as vectors to deliver DNA. 2. DNA ligase is responsible for cutting DNA fragments. 3. Restriction enzymes can create specific DNA cuts.
B
  1. PCR uses DNA ligase to amplify DNA. 2. Plasmids are naturally occurring vectors. 3. Restriction enzymes are used to join DNA fragments.
C
  1. Plasmids act as vectors for DNA transfer. 2. DNA ligase joins DNA fragments. 3. Restriction enzymes create specific cuts in DNA.
D
  1. PCR amplifies DNA using plasmids directly. 2. DNA ligase cuts DNA fragments. 3. Plasmids cannot be used in molecular cloning.

Correct Answer

Option C

Detailed Explanation

Statement 1 is correct as plasmids serve as vectors for DNA transfer. Statement 2 is accurate because DNA ligase is responsible for joining DNA fragments. Statement 3 is also correct as restriction enzymes create specific cuts in DNA, facilitating the joining process.
