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.
385 EXPERIMENT 24 Amplification of a DNA Fragment Using Polymerase Chain Reaction Theory Polymerase chain reaction (PCR) is a techniquethat allows the amplification of a specific fragmentof double-stranded DNA in a matter of hours.ny biological sample recovered from a crime scenethat contains DNA (a single hair, a drop of blood,skin cell, saliva, etc.) can be subjected to PCR.Primers complementary to repetitive DNA se-quences found throughout the human genome arechange a single base pair in the gene of interest(Fig. 24-4 d).
