Theory. Polymerase chain reaction, better known as PCR, is one of the technologies that not only made a tremendous impact on the scientific community, but also affected many aspects of our everyday lives.rogramming PCRs. PCR is an iterative process, consisting of 3 elements; denaturation of the template by heat, annealing of the oligonucleotide primers to the single stranded target sequence(s), and extension of the annealed primers by a thermostable DNA polymerase.
The smallest prime number, according to primality as defined by modern mathematicians, is 2. To be prime, a number must be divisible only by itself and 1. All other numbers are known as composites. Continue Reading.
