Write down with your group:
What are the 3 steps involved in PCR (polymerase chain reaction)?
1.) Denaturation - using heat to split hydrogen bonds and separate the DNA strands
2.) Annealing - as it cools, RNA primers attach to the DNA
3.) Extension - as it is reheated, DNA polymerases build the other sides of the DNA strands
