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.
No, Hardy!â Ramanujan jumped up in bed and exclaimed: âIt is a very interesting number! Itâs the smallest number expressible as the sum of two cubes in two different ways.â (This is because 1729 = 103 + 93 = 123 + 13.) Ramanujan just naturally knew such things, leaving both proofs and details to others.
