- FIGURE 1-5. The polymerase chain reaction. Oligonucleotide primers
- homologous to 3' and 5' regions of the target sequence are used with
- taq polymerase to amplify the target sequence within the template DNA.
- The DNA strands are heat-denatured and the primers are allowed to
- anneal at a specific temperature determined by the length and base
- composition of the primers. The reaction is heated to 72 degrees C to
- allow primer extension by taq polymerase. The newly synthesized
- strands are used as templates in each subsequent cycle such that 30
- cycles produces 2**30 molecules.
