C)a $\lambda$ chromosome in a bacterial cell
D)a bacterial plasmid cut with a restriction enzyme

Question

Quizplus · Accepted Answer

A genomic fragment of human DNA ligated to a bacterial plasmid vector is an example of a recombinant DNA molecule. This is because it involves the combination of DNA from two different sources (human and bacterial) through the use of molecular biology techniques such as restriction enzymes and ligases. The resulting molecule contains genetic information from both sources and is known as a recombinant DNA molecule. The other options do not involve the combination of DNA from different sources and therefore are not examples of recombinant DNA molecules.
