  • Lab coat and disposable gloves
  • PCR reaction mix, 8 tubes, 50 μL each: Mix contains Taq DNA polymerase, MgCl2, and dNTP's (
  • DNA/primer mix, 8 tubes, 50 μL each: Each mix contains a different template DNA. All tubes have the same forward primer and reverse primer
  • A strip of empty PCR tubes
  • Disposable pipette tips: only use each only once. Never re-use disposable pipette tips or samples will be cross-contaminated
  • Cup for discarded tips
  • Micropipettor
  • OpenPCR machine: shared by two groups

DNA Sample Set-up Procedure

  1. Collect a small sample of DNA from cells such as blood, skin, saliva or even hair follicles
  2. Move your extracted DNA sample into a special PCR tube
  3. Add primer 1 to the PCR tube (Primer 1 attaches to a site on the DNA strand at either end of the template segment)
  4. Add primer 2 (which attaches to the 2nd site of the template segment on the DNA strand) to the PCR tube
  5. Add nucleotides to the PCR tube
  6. Add DNA polymerase to the PCR tube
  7. Now place the PCR tube containing all of the reaction components into the DNA thermal cycler
  8. Push start button on DNA thermal cycler

OpenPCR program


INITIAL STEP: 95°C for 2 minutes

Research and Development

PCR - The Underlying Technology

Q1. What is the function of each component of a PCR reaction?

Q2. What happens to the components (listed above) during each step of thermal cooling?

Q3. DNA is made up of four types of molecules called nucleotides, designated as A, T, C and G. Base-pairing, driven by hydrogen bonding, allows base pairs to stick together. Which base anneals to each base listed below?

Adenine-Thymine, Thymine-Adenine, Cytosine-Guanine, Guanine-Cytosine
