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.
Tell your students that each of the circled numbers is a prime number. Explain that a prime number is any number that has only two factors, 1 and itself. It is important to let students know that 0 and 1 are not considered prime numbers. Review the first couple of numbers on the Hundreds Chart as a class, deciding whether each is prime or composite.
