What is the process of linking a piece of DNA with a plasmid called?

Options

  1. ACloning of the desired genes in E. coli
  2. BRecombinant DNA
  3. CTransfer of the DNA to its progeny
  4. DIdentification of DNA with desirable genes

Correct answer

B. Recombinant DNA

Step-by-step solution

In the same way, a plasmid can be used as vector to deliver an alien piece of DNA into the host organism. The linking of antibiotic resistance gene with the plasmid vector became possible with the enzyme DNA ligase, which acts on cut DNA molecules and joins their ends. This makes a new combination of circular autonomously replicating DNA created in vitro and is known as recombinant DNA .
