PCR stands for Polymerase Chain Reaction.

types of pcr: AFLP -PCR.

Allele-specific PCR.

Alu-PCR.

Assembly -PCR.

Assemetric -PCR.

Colony -PCR.

Helicase dependent amplification.

Hot start pCR.

Inverse -PCR.

Insitu -pCR.

ISSR-PCR.

RT-PCR(REVERSE TARNSCRIPTASE).

REAL TIME -PCR

PCR is a biotechnological method to amplify your gene (DNA) of your interest. It produce millions of your DNA fragments hence used in cloning. There are variants of this method using the same thermocycling principle such as touch down PCR, gradient PCR, RFLP, multiplex PCR, Q PCR, RT PCR and so on.

The use of dNTP is PCR and multiplex PCR

to check is there any contamination in pcr products
