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. The temperature of the sample is repeatedly raised and lowered to
help a DNA replication enzyme copy the target DNA sequence. The technique can
produce a billion copies of the target sequence in just a few hours.

polymerase chain reactionThe PCR chain reaction is one of the most important reaction in whole world.It is very important for us.Thanks for regard information.
Great post. Thanks for sharing.Klenow (3′→ 5′ exo-) is a mesophilic dna polymerase deficient in both proofreading (3′→ 5′) and nick-translation (5′→ 3′) nuclease activities, and that displays a moderate strand displacement activity during DNA synthesis.
