Answer:
Polymerase chain reaction (PCR) testing is a laboratory technique used to detect the presence of a particular DNA sequence in a sample. It involves amplifying a small amount of DNA to create multiple copies of the target DNA sequence, which can then be analyzed and detected. PCR testing is commonly used in medical diagnostics, genetic testing, forensic analysis, and research applications. It is a highly sensitive and specific method for detecting DNA and is widely used in the diagnosis of infectious diseases, genetic disorders, and other conditions.
Answer: Using techniques that allows rapid amplification of a specific segment of DNA.
