... DNA to form a base pair. Adenine and thymine bind together to form the A-T base pair. Likewise, guanine and cytosine come together to form the G-C base pair. The bases are joined together by weak hydrogen bonds, and it is this hydrogen bonding that produces DNA's familiar double helix shape. Whatev ...

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.
