Question

which of the following is true about the polymerase chain reaction (pcr)? multiple choice it cuts the dna in specific locations. it carries a copy of a gene into another organism. it can be used to produce millions of copies of a dna fragment. it induces adult cells to behave like stem cells

Explanation:

PCR is a technique used to amplify DNA. It can generate millions of copies of a specific DNA fragment through a series of temperature - controlled cycles. Restriction enzymes cut DNA at specific locations, gene transfer is done by vectors for introducing genes into other organisms, and inducing adult cells to act like stem cells is related to reprogramming techniques.

Answer:

It can be used to produce millions of copies of a DNA fragment.
