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.
Polymerase Chain Reaction (PCR). PCR is a laboratory method used for making a very large number of copies of short sections of DNA from a very small sample of genetic material. This process is called amplifying the DNA and it enables specific genes of interest to be detected or measured.his method is used to measure the amount of DNA that is present in a sample. RT â PCR (Reverse Transcriptase PCR). This method uses PCR to amplify RNA. RNA is a single stranded nucleic acid molecule and needs to be made into DNA before it can be amplified.
