What is DNA sequencing
... Both the Maxam-Gilbert and Sanger-Coulson methods can only produce about 400 bases of sequence at a time. Most genes are larger than this. To sequence a large DNA molecule it is cut up (using two or more different restriction enzymes) into different fragments and each fragment is sequenced in turn 1 ...

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.
