The inspiration comes from my long-term desire to do genetic engineering, and this will be the first major tool on my list to build. My inspiration came from recently seeing a thermocycler/pcr machine built using PVC piping, an incandescent bulb as the heating element, and a computer fan as the cooling element.

What it does

The PCR (Polymerase Chain Reaction) is a reaction used in genetic engineering. It allows the user to get billions of copies of a desired DNA sequence, thus making it easy to work with. It works by heating the DNA to around 95 C, where it gets so hot the DNA unwinds and splits. Then it cools down long enough for the protein polymerase to attach to the unwound strands and create a second strand to match each half. This duplicates the amount of dna. Then the thermocycler heats it back to 95C. Each cycle doubles the amount of the desired strand.
