Question

What is recombinant DNA?

Options

• DNA that has been replicated within a bacterial cell

• DNA that has been transcribed into RNA

• DNA that has mutated during bacterial conjugation

• The product of joining foreign DNA and plasmid DNA, containing the cloned gene

Answer 1

Recombinant DNA is the result of combining foreign DNA (the gene to be cloned) with plasmid DNA using restriction enzymes and DNA ligase. This recombinant molecule contains the cloned foreign gene integrated into the plasmid vector and can be replicated as a single functional unit.
