Answer:
multiple copies of the DNA sample are made.
Step-by-step explanation:
In PCR, multiple copies of the DNA sample are made.
PCR refers to polymerase chain reaction. It is a process that is used in molecular biology to amplify a certain section of a gene or DNA sample so as to study it in details. The process involves making of several copies of small amount of DNA through thermal cycling.
PCR does not determine the sequence of genes and neither does it destroy DNA.
