polymerase chain reaction

Acronym: PCR

Definition Source References

sometimes called molecular photocopying, the polymerase chain reaction (PCR) is a fast and inexpensive technique used to amplify - copy - small segments of DNA. Because significant amounts of a sample of DNA are necessary for molecular and genetic analyses, studies of isolated pieces of DNA are nearly impossible without PCR amplification
