The PCR process has 4 steps :collection, preparation, amplification, and post PCR clean-up. The PCR machine steps happen in the step. It begins with chemicals. The tube is placed into the PCR machine or thermal cycler. The thermal cycler takes the solutior a segment of a DNA sample placed in a suitable tube along with the reagents and through a 3-step process: and Part 2 Descriptlon. Below are NOT arranged in order: The sample mixture DNA polymerase enzyme to bind to the individual strands of DNA that were separated by the heat (this is termed annealing of the primers). At this point, the nucleotides (A, T, C, G) from the added mixture solution will pair with the individual separated strands of is then cooled to between 50 to 60°C (122 to 140°F) allowing the DNA primers and the DNA that resulted from the heating process. Once joined together, they form a new duplicate double-stranded DNA molecule has been formed from each of the single strands of the original sam ple molecule. The temperature cycles from 95°C to 50 to 60°C. The cycle is then repeated about 35 to 40 times using the thermal cycler which automatically repeats the heating and cooling cycles of the new complementary strand of DNA (termed extension of the DNA). Thus, process. The solution contained in the tube is heated to at least 94°C (201.2°F) using a thermal cycler. The heat breaks the hydrogen bonds of the original DNA sample and separates the DNA into single strands (this is termed denaturation of double-stranded DNA). amplification denaturation annealing extension In annealing step: In extension step: In denaturation step:
