Polymerase chain reaction

What is a polymerase chain reaction? Polymerase chain reaction is a technique used to massively multiply DNA, so that it can be analyzed using other techniques. It requires a thermal cycler, filled with the DNA sample to be multiplied, thermostable Taq polymerase, primers with which we select what gets multiplied, and free nucleotides of all 4 types - A, T, C and G. The first step is denaturation, then there’s annealing, and finally extension.
