A polymerase chain reaction (PCR) can be used to produce millions of copies of a targeted piece of DNA. It is an essential tool in modern molecular Biology and has revolutionized scientific research and diagnostic medicine. The PCR and its variants have many specialized applications and are used in all areas of biology. Scientists in many other fields can also use the results.
PCR is useful in understanding many environmental issues, especially where microorganisms are required. PCR molecular analysis allows for the identification and quantification of specific target species even when low numbers are present. One example is the search for pathogens and indicator species, such as coliforms within water supplies.

Personalized genome testing has been possible thanks to PCR. A new industry emerged offering customers tailor-made services and products based on their genetic information. Nutrigenomics, for example, is a special form of consumer genomes that links genetics to information about foods that may be better or worse in particular conditions like IBS.
PCR is essential for the identification and collection of organic crime scene evidence, such as blood, hair and pollen. PCR can be used to forensically identify DNA fingerprints and determine familial relationships. PCR can identify DNA from very small samples. A single molecule DNA can suffice for PCR amplification.
PCR has allowed for many important developments in medical fields. It is used for diagnosis and treatment of many disorders. It is also widely used in research to determine the diagnosis and treatment options. The polymerase chain reactions (PCR) is a very simple and useful molecular biology procedure.
