Transcription factors (TFs) bind specific sequences in promoter-proximal and -distal DNA elements to regulate gene transcription. RNA is transcribed from both of these DNA elements, and some DNA binding TFs bind RNA. Hence, RNA transcribed from regulatory elements may contribute to stable TF occupancy at these sites.

Presently, there is much more data on the role of self-regulation in writing than there is on the impact of basic transcription skills. This is probably due to the heavy empha-sis placed on the cognitive and self-regulatory aspects of

Regulation of Gene Expression by the Structure of Chromatin. In eukaryotic cells, DNA is contained within a discrete or-ganelle called the nucleus, which is the site of DNA replica-tion and transcription. Within the nucleus, chromo-somes—which are extremely long molecules of DNA—are wrapped around histone proteins to form nucleosomes, the ...

Frequently they are activated in the cytopl asm and then translocated to th e nucleus, where they form a heterodimer with RXR. These receptors are thir d class of nuclear hormone receptors, called xenoreceptors (XR) or xenosensors (Xu et al., 2005).

Model of Transcriptional Regulation We assume that the transcription rate of an operon is proportional to the fraction of time RNAP is bound to the promoter [1,12–14]. The model we use to compute this quantity is illustrated in Figure 3. The RNAP-r binds only to the 10 and 35 hexamers, called the core promoter, and we
