Document Summary
Topic 7 - transcription (dna to rna) and regulation. Understand, describe and demonstrate the steps involved in transcribing. Within the promoter there is there is a regulating element called an operator: genetic transcription begins when rna polymerase locates the promoter on the sense strand of. Pre-mrna contains several segments that aren"t involved in the coding of the resulting protein. If introns are translated, the protein won"t fold properly-making the protein dysfunctional. Before pre-mrna leaves the nucleus, introns are removed by spliceosomes. They recognizes the sequences that signal the start and stop of the splicing. Compare and contrast rna transcription in prokaryotes vs eukaryotes. Both: in a prokaryotic cell, transcription continues through the entire length of the operon, all transcription is performed by a single type of. In initiation, rna polymerase rst recognizes the promotor site at -35 region and binds to full promotor. Rna polymerase binds more tightly to the promotor.
