1 Breathe in deeply through your nose, expanding your abdomen and then filling your lungs with air. 2  Hold your breath for a couple of seconds. 3  Breathe out slowly through your mouth and empty your lungs completely.  Repeat for 5 to 10 minutes.
PCR is the enzymatic amplification of a specific DNA sequence in vitro9. This process uses multiple cycles of template denaturation, primer annealing, and primer elongation to amplify DNA sequences. It is an exponential process since the amplified products from each previous cycle serve as templates for the next cycle of amplification,
Polymerase chain reaction (PCR) is one of the most widely used enrichment strategies for over 20 years. PCR is technology to amplify specific DNA sequences. It uses a single stranded piece of DNA as a start for DNA amplification.t consists of first selecting only the subset of DNA that encodes proteins (known as exons), and then sequencing that DNA using any high throughput DNA sequencing technology.
