Scientists Identify Key Roadblock to Gene Expression
Credit: B. Franklin Pugh, Penn State In yeast, a nucleosome sits on top of the transcription start site, so RNA polymerase must contend with that nucleosome as soon as it begins to transcribe the gene. In contrast, nucleosomes are positioned further downstream in fruit flies, so transcription starts but then soon pauses at the first nucleosome RNA polymerase encounters.
