Polymerase chain reaction steps ( PCR ), principle, procedure

Here you will learn, what is PCR, and what are the Polymerase chain reaction steps. PCR is the short name of polymerase chain reaction. It plays a vital in the diagnosis of fatal diseases like covid-19, Hepatitis C virus, Human Immunodeficiency virus, and many others.

PCR (Polymerase Chain Reaction) method used to detect the DNA of certain pathogens like COVID-19, Hepatitis B virus, Hepatitis C virus, and other such polymerase chain reactions. Polymerase Chain Reaction is also used in the research field for research purposes. PCR (Polymerase Chain Reaction) gives a hundred percent accuracy in the result. 

It is essential for DNA synthesis.

Here is the PCR (Polymerase Chain Reaction) 4 steps cycle. . A list of four steps of PCR is there. 

DENATURATION 

ANNEALING

In this step, the temperature drops to 75C. In this phase primer bind with complements with sequencing order on DNA single strand. Mostly Annealing temperature set between 50 and 75 Centigrade for 30 seconds to one minute. 

EXTENSION

END OF CYCLE

This is the final step of the polymerase chain reaction. After the synthesis of two identical strands, the PCR cycle was completed.
