1. Denaturation step is the step to make DNA a single line double a. Based on heat, temperature is around 90-95° c. 2. Primer annealing steps are steps that reduce the temperature down to about 45-60 degrees Celsius so that the Primer can cling to a single line of template DNA where a double bass sequence with Primer. 3. Primer extension step is a step to expand the DNA cables from 5 ' to 3 ' direction on the basis of enzyme Taq DNA polymerase, Thermostable polymerase, which is normally used at the temperature in the range of $ 70-75 degrees Celsius. Gel electrophoresis, PCR, producing effects that are generated from DNA isolated from small eyes. Using electric current DNA on Agarose gel or Polyacrylamide gel in comparison with standard DNA that know the exact size, then dye Ethidium bromide with DNA chips, to borrow the show with light-violet lotra. The output PCR use pieces of DNA that are clear and meets size requirements, but if it is smaller, and the DNA is unclear, it might be a DNA Primer-dimer.
