PCR (polymerase chain reaction) is a technique using small amounts of DNA replication to create large amounts of DNA for analysis. It is commonly used in forensic analysis because it requires the smallest amount of sample compared to other DNA analysis techniques such as RFLP (restriction fragment length polymorphism) and Southern blot. Genomic DNA and cDNA isolation also require larger amounts of sample compared to PCR.
