When epigenetics meets alternative splicing: the roles of DNA
... The process of pre-mRNA splicing has been studied for more than 30 years, yet it is far from being fully understood. Accumulating evidence suggests that many splicing events occur cotranscriptionally and that the mRNA precursor remains associated with the chromatin until all of the introns have been ...

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.
