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.
Polymerase Chain Reaction (PCR) PCR can be used in DNA fingerprinting as a way to make numerous copies of isolated DNA. The process can selectively amplify a single copy of a desired sequence.First Cycle: -Dna molecules are melted by raising the temperature to 95 degrees Celcius.his process is called blotting. Finally, radioactive probes get washed over the nylon surface. These probes will join to any DNA fragments that share the same composition. The final step to making a genetic fingerprint is to place a photographic film on top of the nylon surface.
