Polymerase chain reaction (PCR) is a method used to rapidly produce multiple copies of a specific DNA segment. The process involves cycles of heating to separate the DNA strands and cooling to allow primers to bind and facilitate new DNA strand synthesis. This technique enables the amplification of DNA in a short period of time.

1. Solution
:
Polymerase chain reaction is process in which several copy of specific segment of DNA can be
produced within short interval of time.PCR include various cycles of heating and cooling.DNA
is double stranded structure.Initially,DNA molecule is heated to divide it into two single
strands.Then under lower temperature condition short strand of DNA which start its synthesis are
attached to DNA template.After that temperature is increased and new strand of DNA is formed.
