Question

the polymerase chain reaction (pcr) makes many copies of a gene or other dna segment. check it

Explanation:

The polymerase chain reaction (PCR) is a widely - used technique in molecular biology. Its main function is to amplify (make many copies of) a specific gene or other DNA segment. This is achieved through a series of temperature - controlled cycles. In each cycle, the DNA is denatured (separated into single strands), primers anneal (bind) to the target DNA regions, and DNA polymerase synthesizes new strands. Through multiple cycles, the amount of the target DNA segment (gene or other DNA) increases exponentially.

Answer:

TRUE
