step 1-taking a sampling step 2-the sample is processed and DNA is taken from the samples, the DNA is then added to a PCR cocktail,It is then placed into a thermocycler for amplification,the next thing is the double helix splits apart. This is done by heating the sample to 95 degrees Celsius step 3-it is cooled to 45-60 degrees Celsius. The two single stranded primers find their complementary DNA sequences and bond to them step 4-The thermostable polymerase catalyzes the addition of complementary bases to the single stranded template DNA. This forms two new double-stranded DNA helix. These three stages of PCR amplification are then repeated over and over (up to 40 times).
Princples and Procedures of PCR.
PCR is used to amplify specific regions of the DNA strand. This can be a single gene, part of a gene, or a non-coding sequence. Most PCR methods typically amplify DNA fragments of up to 10 kilo base pairs(kb), though some techniques allow amplification of fragments up to 40 kb in size.A basic PCR set up requires several components and reagents.
