What does polymerase chain reaction do
2 answers:
Answer:
The polymerase chain reaction is a method used to produce millions of copies of particular DNA.
DNA sequences are amplified to generate many copies of a specific DNA segment.
Explanation:
polymerase chain reaction is used to produce a million copies of DNA by amplifying the DNA sequences exponentially.
PCR method was developed in 1983 by Kary Mullis .
A polymerase chain reaction occurs in three main steps.
Denaturing : In this step, double-strand template DNA is separated into two single strands by heating.Annealing : DNA primers get attach to the DNA template when the temperature is lower.Extending : with the help of the Taq polymerase new strand is synthesis which is complementary to the template DNA.thus polymerase chain reaction is used to produce many copies of DNA of specific region of DNA.
Sometimes called molecular photocopying the polymerase chain reaction is a fast and inexpensive technique used to amplify copy small segments of DNA.
