Answer:
it is used to generate multiple copies of a particular DNA section .
Explanation:
polymerase chain reaction is used to generate multiple copies of a particular DNA fragment.
Steps involved in the polymerase chain reaction
- Denaturation in this process DNA strand is heated and it is separated into two DNA single strands
- Annealing in this step DNA primers gets attach to the template DNA, while the temperature is lower.
- Extension new stand is synthesis by increasing the temperature with the help of enzyme Taq polymerase.
