4. Several “ingredients” other than the DNA sample must be added to the reaction tube in order for PCR to work

Several “ingredients” other than the DNA sample must be added to the reaction tube in order for PCR to work properly. Name 3 of these ingredients and describe their roles in the polymerase chain reaction

1) DNA template- DNA molecule containing the segment of DNA to amplify.
2)Primers- small pieces of DNA (8-25 bases long that bind to complementary regions on opposite strands of the template. The primers serve as replication start points. Two primers are used to amplify one location in PCR.
3)DNA polymerase (AmpliTaq)- enzyme used to replicate DNA. It adds bases onto the 3' ends of the annealed primers. This polymerase is stable at high temperatures because it was taken from a bacteria that thrives in hot springs.
4)Magnesium chloride- Magnesium is a cofactor for DNA polymerase. Without magnesium the polymerase will not work.
5)dNTPs(deoxynucleoside triphosphates)- the nucleotides added onto the annealed primer by DNA polymease.
6)Buffer- maintains pH of the reaction at a lvl where the DNA polymerase is most active
