Gene transcription occurs on a nucleosomal template known as chromatin. The recruitment of the transcriptional regulators and the transcription machinery to promoter chromatin is coordinated by a genetic code on the DNA and an epigenetic code on the histone proteins. Chromatin is not a stable environment; rather, the histones, the transcription regulatory proteins and the enzymes that modify and mobilise nucleosomes are in a dynamic state. Thus, at any one time, the factors associated with a… CONTINUE READING
