Transcription Termination and Its Control, the central models to understand the biochemical mechanisms of these processes. The notable conservation of the two large major subunits of RNA polymerase between bacterial RNAP and all three eukaryotic enzymes,. and the fact that termination is at least partly a function of these subunits,. sugges

Control by Antisense RNA,n of those RNAs post-transcriptionally. Antisense RNA control is well documented in bacteria, especially in their accessory elements—plasmids, bacteriophages and transposable elements (see Table 5.1). In all of these cases, control is negative. However, mechanisms for positive control are quite plau

Translational Control of Gene Expression in , and Bacteriophage,ponse to a specific need at a given stage of the cell cycle or development. In many cases, the regulation is transcriptional. The discovery that translation is a level of gene expression at which regulation can take place goes back to the observation that transcription is not necessary for early pha

Effects of DNA Supercoiling on Gene Expression,mplate. The effects of template supercoiling on the kinetics of transcription are, however, much more complex even in simple cases involving no regulatory factors; a priori predictions of such effects are at best tenuous. In this chapter, we focus on insights gained from experimental data accumulate

The HU and IHF Proteins: Accessory Factors for Complex Protein-DNA Assemblies,teins acting at a DNA locus that encompasses 30–50 bp. However, such a simple picture is not usually (if ever) the whole story. Much more common are complex systems that typically involve several proteins acting over much larger segments of DNA. At these extended loci, one finds that function depend
