Synthesis and Release of Protein
... Replication begins with the uncoiling of the DNA helix. Once this has happened, the weak hydrogen bonds joining the two strands break, causing the DNA molecule to ‘unzip’. Once the bases are exposed, free nucleotides find their complimentary bases, forming two new DNA molecules, identical to the ori ...

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.
