PCR Steps and Reaction Setup

Description

PCR uses thermocycling to make many copies of DNA. Thermocycling means repeating cycles of temperature changes at fixed time intervals. With a thermostable DNA polymerase and DNA building blocks called dNTPs, the reaction can produce numerous copies from a small DNA sample.

The PCR cycle has thre...

Transcript

The polymerase chain reaction or PCR is a widely used method for amplifying DNA fragments. PCR uses thermocycling, which is the repeated heating and cooling of the reaction via three distinct temperatures called denaturation, annealing and extension or elongation.

The thermocycling reaction b...
