The Polymerase Chain Reaction (PCR): Cloning DNA in the Test Tube
The polymerase chain reaction is a technique for quickly "cloning" a particular piece of DNA in the test tube (rather than in living cells like E. coli).

Definition of polymerase : ...
The method amplifies specific DNA segments by cycles of template denaturation; primer addition; primer annealing and replication using thermostable DNA polymerase.
Polymerase Chain Reaction (PCR)
Polymerase chain reaction (PCR) is a laboratory technique used to amplify DNA sequences. The method involves using short DNA sequences called primers to select the portion of the genome to be amplified.
Polymerase Chain Reaction (PCR)
The technique of PCR permits the selective amplification of a specific segment of DNA or RNA. Some sequence information must be known prior to PCR so that primers flanking the segment of interest can be synthesized.
Polymerase: Polymerase is an enzyme that ac ts like a molecular assembly line to build new strands of DNA.
