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.
Recombinant DNA and genetic techniques. Recombinant DNA (or rDNA) is made by combining DNA from two or more sources. In practice, the process often involves combining the DNA of different organisms.here are two types of gene cloning: in vivo, which involves the use of restriction enzymes and ligases using vectors and cloning the fragments into host cells (as can be seen in the image above). The other type is in vitro which is using the polymerase chain reaction (PCR) method to create copies of fragments of DNA.
