to check is there any contamination in pcr products
2 main precautions while performing a pcr reaction: - Avoiding contamination of the samples by DNA; - Thawing all the components thoroughly at room temperature after storage and mixing them in a centrifuge briefly. If the precautions are not followed while performing a pcr mastermix you may end up with no results or bands in negative control. Thank you.......
enzyme cofactor
One can use a PCR to amplify and quantify a certain DNA molecule. A TaqMan real-time PCR is a certain type of PCR which uses the TaqMan method to increase its specificity.
The enzyme DNA polymerase ( Taq polymerase) used in the PCR requires Mg 2+ ions for its functioning.These Ions act as cofactors for the enzyme . Hence the requirement for the use of Mg Cl2 in PCR reactions.
We use this principe when the annealing temperature of the two primers (reverse and forward) is different
The use of dNTP is PCR and multiplex PCR

PCR, unlike culture, does not require viable (live) bacteria present in the specimen. Results can be had in 2-3 hours instead of 24-36 hours. Despite these advantages, PCR can give results that are falsely-negative or falsely-positive.
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 an enzymatically guided process. In optimum pH the enzyme will work best.

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.
