Why was polymerase chain reaction developed?

Answer 1

makes more copies of a sample of DNA. apex

Answer 2

PCR is used to amplify DNA in a rapid and convenient way. If you only have a very limitted quantity of DNA molecules, and you want to make lots of them, PCR is the way to go. All you need is the DNA sample you want to make lots of copy of, primers, DNA polymerase (enzyme that will make the DNA), and the single nucleotide dNTPs (building blocks of DNA).

Answer 3

Polymerase Chain Reaction (PCR) testing is a technique to amplify a single or few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence. This allows for easier identification of particular DNA segments and can be used to assist in the diagnosis of certain diseases.

Answer 4

The polymerase chain reaction (PCR) is used to amplify DNA samples so there are enough copies present to do further experiments.
