PCR allows for the analysis of DNA fragments through the comparison of the base pairs each molecule contains, which can then be used for genetic screening and the identification of individuals and DNA fragments
PCR stands for Polymerase Chain Reaction, and it speedily copies DNA millions of times. It has been used in DNA sequencing since the DNA sample is sometimes too small.
What is PCR?
PCR is an abbreviation for polymerase chain reaction. It's a tool for determining genetic material from a given species, such as a virus.
Whether you have the virus at the time of testing, the test detects its inclusion.
PCR involves selecting a portion of the genome to be augmented using short artificial DNA fragments called primers, followed by a series cycles of DNA synthesis to amplify that segment.
Its principle is based on the replication of specific DNA sequences in vitro using DNA polymerase.
From a DNA extract, this method can generate tens of billions of copies of a specific DNA fragment.
Thus, PCR has been used during the sequencing of DNA since the DNA sample is sometimes too small.
