The Mechanics Of Gene Transcription

The molecular machinery behind gene transcription — the intricate transfer of information from a segment of DNA to a corresponding strand of messenger RNA — isn’t stationed in special “transcription factories” within a cell nucleus, according to Cornell researchers. Instead, the enzyme RNA polymerase II (Pol II) and other key molecules can assemble at the site of an activated gene, regardless of the gene’s position.
