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.
Conversely the period of the repeating decimal of a fraction c / d will be (at most) the smallest number n such that 10 â 1 is divisible by d. For example, the fraction 2/7 has d = 7, and the smallest k that makes 10 â 1 divisible by 7 is k = 6, because 999999 = 7 Ã 142857.
