Annealing primers

Annealing primers can be used as a fast and cheap way to synthesize a short piece of DNA for which you do not have template DNA to PCR from. See part fabrication for other ways to make a part (contains BioBrick specific details).
 * 1) Annealing complementary primers<--For pieces of DNA shorter than the limit on primer length.
 * 2) Annealing and primer extension<--For pieces of DNA longer than the limit on primer length.
