What is the significance of the cloning of antibiotic resistance gene in E. coli?

Options

  1. AIt allowed for the maintenance of introduced DNA in the host and transfer to its progeny
  2. BIt facilitated the identification of DNA with desirable genes
  3. CIt demonstrated the process of linking a piece of DNA with a plasmid
  4. DIt demonstrated the ability to multiply copies of a specific gene

Correct answer

D. It demonstrated the ability to multiply copies of a specific gene

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 . .
