Abstract

By thinking about the chemical and physical mechanisms that are involved in the stepwise elongation of RNA transcripts, we can begin to understand the way that these mechanisms are controlled within the cell to reflect the different requirements for transcription that are posed by various metabolic, developmental and disease states. Here, we focus on the mechanistic details of the single-nucleotide addition (or excision) cycle in the transcription process, as this is the level at which many regulatory mechanisms function and can be explained in quantitative terms.
