.

Researchers demonstrated that many different DNA fragments could insert into a plasmid vector.

.

This technique was developed in by Kary Mullis, an American biochemist. This tool is commonly used in the molecular biology and biotechnology labs. Therefore, a primer is required. It is thermostable and does not denature at very high temperatures. Deoxyribonucleotide triphosphate — These provide energy for polymerization and are the building blocks for the synthesis of DNA. These are single units of bases. It is also important for fidelity, polymerase activity, and stability. In this type, the DNA amplification is detected in real-time with the help of a fluorescent reporter. The signal strength of the fluorescent reporter is directly proportional to the number of amplified DNA molecules.

Polymerase chain reaction is commonly known as PCR. It is used to produce multiple copies of a gene or DNA of interest. The steps of polymerase chain reaction are denaturation, primer annealing and extension of primers. It is done in vitro using a primer. This technique is used in labs to make billions of copies of the desired gene for research, diagnostic and therapeutic purposes. PCR was invented by Kary Mullis in In the polymerase chain reaction, the reaction cycle is repeated many times to get billions of copies.
