The process of genetic engineering may include either four or five steps. The diagram represents the five-step process. Which best describes step 2?
A) Restriction enzymes cut the DNA into fragments; the fragments join with the host DNA to create recombinant DNA.
B) Recombinant DNA is inserted into a biological vector; the vector houses the recombinant DNA and can produce copies of DNA for itself and the recombinant DNA.
C) Cloning of the recombinant DNA occurs; the DNA is cloned in the biological vector to create more DNA for use in the host.
D) Recombinant DNA is inserted into a mechanical vector; the mechanical vector allows the DNA to be inserted into the DNA clone for use in the host.
