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. Polymerase chain reaction, or PCR, is a laboratory technique used to make multiple copies of a segment of DNA. PCR is very precise and can be used to amplify, or copy, a specific DNA target from a mixture of DNA molecules.hen, to perform PCR, the DNA template that contains the target is added to a tube that contains primers, free nucleotides, and an enzyme called DNA polymerase, and the mixture is placed in a PCR machine. The PCR machine increases and decreases the temperature of the sample in automatic, programmed steps.
