I will try to make you understand the matter in an easy way.... Downloaded from Shutterstock. Polymerase Chain Reaction Polymerase chain reaction is a technique, used in molecular biology to amplify a single copy or few copies of particular DNA sequence. When there is a small amount of DNA then we use the method or technique for further analysis the DNA. Which can generate thousand to millions copies of particular DNA sequence. A basic PCR setup required several components and reagents. when we use the technique in the lab then we first prepare a mixture of a reaction ...... The picture is downloaded from Shutterstock.   1. At the first we need a DNA template for amplification. 2. Primers ( primers are short oligonucleotide sequence which are 15 to 20 nucleotide long ) two DNA primers that are complementary to the t...
