DNA SEQUENCING AND GENE STRUCTURE
... The logic behind the chemical method is to divide the attack into two steps. In the first we use a reagent that carries the specificity, but we limit the extent of that reaction - to only one base out of several hundred possible targets in each DNA fragment. This permits the reaction to be used in t ...

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.
