In the meantime, here's a sneak peek, just a small sliceâthe first part of a 2-part excerpt from the addendum of Grantsmanship: Program Planning & Proposal Writing. The topic is the difference between a planning and an implementation (or program) grant proposal. Enjoy!
What is PCR (polymerase chain reaction)? Polymerase chain reaction (PCR) is a technique that is used to amplify trace amounts of DNA (and in some instances, RNA) located in or on almost any liquid or surface where DNA strands may be deposited.
An Overview of the PCR Lab Test. The PCR lab test (polymerase chain reaction) was developed to overcome the obstacle of quickly replicating DNA for research use. Developed in the 1980s, the PCR lab test is widely applied in medicine, from identifying new viruses to testing for bacterial illness. An alternate application is criminology, where it is used to help find potential perpetrators.
