If you're shooting a university's graduation, then odds are that most of the people in attendance are from out of town and plan to leave soon. In addition to the camera, tripod and flash, you should also have a great photo printer so that you can deliver the goods on the same day.
Polymerase chain reaction. Polymerase chain reaction, (PCR), a technique used to make numerous copies of a specific segment of DNA quickly and accurately.
Report Abuse. PCR The polymerase chain reaction (PCR) is a technique widely used in molecular biology. It derives its name from one of its key components, a DNA polymerase used to amplify a piece of DNA by in vitro enzymatic replication.As PCR progresses, the DNA thus generated is itself used as template for replication. This sets in motion a chain reaction in which the DNA template is exponentially amplified.With PCR it is possible to amplify a single or few copies of a piece of DNA across several orders of magnitude, generating millions or more copies of the DNA piece.ith PCR it is possible to amplify a single or few copies of a piece of DNA across several orders of magnitude, generating millions or more copies of the DNA piece.
