DNA Structure: Gumdrop Modeling
... To make one DNA molecule into two, the bonds between the bases (the rungs of the ladder) are broken by an enzyme called DNA helicase (depicted as scissors below). Once the strands are separated, newly made nucleotides can be brought in and paired up with each individual strand by another enzyme, DNA ...

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.
