What is PCR and how is it used?

Sometimes called "molecular photocopying," the polymerase chain reaction (PCR) is a fast and inexpensive technique used to "amplify" - copy - small segments of DNA.

Likewise, people ask, what is PCR cycle sequencing?

PCR is being used in an ever increasing number of new techniques. There are two basic differences between cycle sequencing and PCR amplification. The first is the presence of only one primer in the cycle-sequencing reaction used to prime synthesis of one strand of the DNA.

Is PCR used in gene sequencing?

PCR stands for Polymerase Chain Reaction, and in short, it copies DNA millions of times very quickly. It is used in DNA sequencing because sometimes the DNA sample is too small. This happens, for instance, in crime scene evidence, or in very old samples (eg. mummies).
