The polymerase chain reaction allows us to amplify the tiny amounts of the dna, creating a powerful tool for diagnosis, forensics, and microbial investigation
Polymerase chain reaction (abbreviated PCR) is the laboratory technique for the rapidly producing (amplifying) millions or billions of the copies of a specific segment of the DNA, which can be then be studied in the greater detail PCR is a very powerful and the significant analytical tool to use for the forensic DNA typing because of the researchers only they need a very small amount of the target DNA to be used as for analysis. For example, a single human hair with the attached hair follicle has the enough DNA to be conduct the analysis.
