Polymerase Chain Reaction (PCR)
... Polymerase chain reaction, or PCR, is a technique used to take a piece of DNA and make many copies of it. This technique is very similar to the natural process which cells use to make new copies of DNA, but it is also a little different. Scientists use an enzyme called taq polymerase which can conti ...

Replisome
The replisome is a complex molecular machine that carries out replication of DNA. The replisome first unwinds double stranded DNA into two single strands. For each of the resulting single strands, a new complementary sequence of DNA is synthesized. The net result is formation of two new double stranded DNA sequences that are exact copies of the original double stranded DNA sequence.In terms of structure, the replisome is composed of two replicative polymerase complexes, one of which synthesizes the leading strand, while the other synthesizes the lagging strand. The replisome is composed of a number of proteins including helicase, RFC, PCNA, gyrase/topoisomerase, SSB/RPA, primase, DNA polymerase I, RNAse H, and ligase.
