WebFeb 23, 2007 · Main Text Introduction. Ever since chromatin structure was recognized as a repeating unit of histones and approximately 200 bp of DNA (Kornberg and Thomas, 1974), it has been speculated that its function extends beyond simple DNA compaction.Indeed, the discovery that nucleosomes impede transcription in vitro (Knezetic and Luse, 1986, … WebJun 10, 2016 · First, the chromatin template slows down transcription at the gene end. Then, the transcript is cleaved at the poly(A) signal to release the messenger RNA. The remaining transcript is selectively unraveled and degraded. This induces critical conformational changes in the heart of the enzyme that trigger termination. Termination … WebNov 19, 2024 · To directly observe the structural differences between SIR chromatin fibers, we visualized fibers by AFM.
