What is the role of DNA polymerase enzyme in the replication of recombinant DNA?

Options

  1. AIt acts as a mechanism to transfer a piece of DNA into a host organism
  2. BIt acts as a vector to deliver an alien piece of DNA into the host organism
  3. CIt makes multiple copies of the recombinant DNA
  4. DIt acts as a type of bacterium

Correct answer

C. It makes multiple copies of the recombinant DNA

Step-by-step solution

When this DNA is transferred into Escherichia coli, a bacterium closely related to Salmonella, it could replicate using the new host’s DNA polymerase enzyme and make multiple copies. The ability to multiply copies of antibiotic resistance gene in E. coli was called cloning of antibiotic resistance gene in E. coli.
