Are used to remove a desired gene from the dna sequence of an organism. select one: a. polymerase chain reaction (pcr) b. plasmids c. gel electrophoresis d. restriction enzymes e. dna probe

The correct answer is:  D-restriction enzymes.

A restriction enzyme is a DNA-cutting enzyme that cleaves DNA into fragments. Each restriction enzyme recognizes one or a few target sequences-restriction sites. It is the site where the DNA is cleaved by the enzyme.

In DNA cloning, restriction enzymes with some other enzymes are used to insert genes and other pieces of DNA into plasmids.
