WebOverview of the Stages of Transcription. The basic steps of transcription are initiation, elongation, and termination. Here we can identify several of the DNA sequences that characterize a gene. The promoter is the binding site for RNA polymerase. It usually lies 5’ to, or upstream of the transcription start site. In genetics, a transcription terminator is a section of nucleic acid sequence that marks the end of a gene or operon in genomic DNA during transcription. This sequence mediates transcriptional termination by providing signals in the newly synthesized transcript RNA that trigger processes which release the transcript RNA from the transcriptional complex. These processes include the direct interaction of the mRNA secondary structure with the complex and/or the indirect activities …
