PCR (Polymerase Chain Reaction)
What are the 4 steps of PCR?
How does PCR work? To amplify a segment of DNA using PCR, the sample is first heated so the DNA denatures, or separates into two pieces of single-stranded DNA.
Next, an enzyme called "Taq polymerase" synthesizes - builds - two new strands of DNA, using the original strands as templates.
How PCR works?
A standard polymerase chain reaction (PCR) setup consists of four steps:
1Add required reagents or mastermix and template to PCR tubes.
2) Mix and centrifuge.
3) Amplify per thermo cycler and primer parameters.
4) Evaluate amplified DNA by agarose gel electrophoresis followed by ethidium bromide staining.How to do a PCR reaction?
Polymerase chain reaction, or PCR, is a laboratory technique used to make multiple copies of a segment of DNA.
PCR is very precise and can be used to amplify, or copy, a specific DNA target from a mixture of DNA molecules.
Polymerase Chain Reaction (PCR)
PCR involves using short synthetic DNA fragments called primers to select a segment of the genome to be amplified, and then multiple rounds of DNA synthesis to amplify that segment.
