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.
The Polymerase Chain Reaction (PCR) is an important tool for many applications. For example, it can be used to amplify a sample of DNA when there isnât enough to analyze (e.g. a sample of DNA from a crime scene, archeological samples), as a method of identifying a gene of interest, or to test for disease.rimers complementary to particular regions of the DNA of interest are added to a sample along with the enzyme DNA polymerase. A complementary strand of DNA is built using the primer as the initial building block.
