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.
Let's try the next prime number, 3: 147 Ã· 3 = 49. That worked, now we try factoring 49, and find that 7 is the smallest prime number that works: 49 Ã· 7 = 7. And that is as far as we need to go, because all the factors are prime numbers. 147 = 3 Ã 7 Ã 7 (or 147 = 3 Ã 7 2 using exponents)
