... What is “transcription?” • A part of the DNA double helix within the nucleus is unzipped, cut by enzymes, and then copied onto a new single strand, called mRNA. This process is called “transcription.” • Once the DNA is transcribed, the single strand moves from the nucleus to a ribosome in the cytop ...

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.
