Sample Prep for Denaturing PAGE of DNA
... DNA samples for denaturing gel electrophoresis must be denatured prior to loading, to avoid time dependent denaturation artifacts on the gel. This is usually carried out by diluting the sample into 95% formamide and heating to 95°C, see the Dideoxy Sequencing (Taq Polymerase) Protocol for a formula ...

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.
