Polymerase chain reaction (PCR) is a method widely used in molecular biology to make many copies of a specific DNA segment. Using PCR, a single copy (or more) of a DNA sequence is exponentially amplified to generate thousands to millions of more copies of that particular DNA segment. PCR is now a common and often indispensable technique used in medical laboratory and clinical laboratory research for a broad variety of applications including biomedical research and criminal forensics . PCR was developed by Kary Mullis in 1983 while he was an employee of the Cetus Corporation. He was awarded the Nobel Prize in Chemistry  in 1993 (along with Michael Smith) for his work in developing the method.

Micro-organisms affect every aspect of life on Earth. Some microbes cause disease but the majority are completely harmless.
These minute life forms are essential to the cycling of nutrients in the eco-systems of the planet.
We need to understand the role of microbes in global terms, but there are many aspects of our daily lives where knowledge of microbiology can help us answer everyday questions such as
How can I avoid flu?
Should I have the HPV vaccine?
Should I take probiotics?
How is yoghurt made?
What precautions do I need to take to stay fit and healthy when travelling abroad?
