Functions and Uses of the Polymerase Chain Reaction (PCR)
The polymerase chain reaction is a process of increasing or enlarging extremely small amounts of DNA so that they can be seen or can be used in various scientific processes. PCR is generally used in various branches of biology, food science, and forensic science, environmental science and many more. There are several techniques used in medical and biological research, which includes diagnosis of hereditary diseases, identification of fingerprints, and to detect infectious diseases. DNA forensics relies heavily on PCR. PCR is considered as one of the most suitable DNA testing methods. This is basically used to classify the DNA of a person by using extremely small samples. How is this possible? This is possible because the device will increase the size of DNA that will somehow be visible to the eyes of the person performing the tests. This process is perfect for legal investigations and crimes. This is because there are fewer samples and other techniques would not be able to detect DNA ...
