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.
