Molecular biology made easy. The polymerase chain reaction

Conclusion PCR is an exciting, versatile technique which already has an established role in biological and medical research. Increasing automation and standardization of procedures will lead to wider applications on the routine workbench. The exquisite sensitivity of the PCR means that strict precautions must be taken to avoid misleading results. However, an awareness of the potential problems, combined with care in the application and execution of the PCR, should greatly enhance molecular biological research.
