DNA polymerase makes the lagging strand by using a new RNA primer for each Okazaki fragment it encounters.
[6] Polymerase chain reaction (PCR) is a method used in laboratories that significantly increases the production of replicated DNA sequences.
PCR has revolutionized science by allowing laboratories to replicate up to billions of DNA sequences in only a few hours.
[7] This method has been used to diagnose diseases, sequence and clone genes, detect pathogens, and locate criminals.
During PCR, two primers will bind to opposite template strands of DNA.
