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.
PCR stands for Polymerase Chain Reaction.
PCR
Since the point of PCR is to amplify a copy of DNA, it would result in many copies of DNA that you want to study.
It is a special type of PCR amplification, that contains the normal external primer for PCR and 2 extra primers specific for each different base of a SNP.
Template DNA is a DNA you want to amplify. So you should know what you are amplifying before a PCR or you can make it by sequencing your PCR product.
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
there are; 1. RT PCR - helps in making complementary DNA with the help of mRNA. 2.anchored PCR - helps in making the DNA whose sequence is unknown.
The use of dNTP is PCR and multiplex PCR
PCR stands for Polymerase Chain Reaction.
Difference between real time PCR and reverse transcription PCR is as follows:- 1. Real time PCR is donated as qPCR and on the other hand reverse transcription PCR is denoted as RT-PCR. 2. In qPCR, the template used is single strand DNA strand whereas in the RT-PCR, the template used in process is single strand of RNA. 3. The real time PCR enables both quantification as well as detection of the DNA in the real time whereas the RT-PCR enables only the quantification of the RNA and it is little bit slower process then the qPCR as it first produce the cDNA from the template RNA strand and then process it in the similar fashion as the traditional PCR.
to check is there any contamination in pcr products
It Inhibits the PCR reaction by chelating the magnesium ions.

The choice of primers controls which DNA is amplified in PCR.

what is the difference between PCR simplex and multiplex
PCR allows amplification of DNA for a specific gene, after too many cycles of PCR the result will reach saturation, basically meaning all of the DNA has been amplified. Conventional PCR will basically tell you whether or not a gene is expressed in your sample. This can be done semi-quantitavely if the PCR is performed for a low number of cycles, ie it will tell you whether one sample expresses more of your gene of interest than another sample. The results are seen by separating the PCR products by agarose gel/ethidium bromide electrophoresis. Real-time PCR will record exactly what cycle of PCR a detectable level of amplified product became detectable, giving a far more accurately quantifiable estimation of gene expression.
