Copying occurs at a localized region called the replication fork, which is a Y shaped structure where new DNA strands are synthesised by a multi-enzyme complex. Here the DNA to be copied enters the complex from the left. One new strand is leaving at the top of frame and the other new strand is leaving at bottom. The first step in DNA replication is the separation of the two strands by an enzyme called helicase.
PCR (polymerase chain reaction) denotes a process that is used to replicate DNA. The first step in PCR, known as denaturing, involves heating a DNA sample to separate its two strands. Once separated the two strands are used as templates to synthesise two new DNA strands. This is done with the help of an enzyme called Taq polymerase.
