Document Summary
Learning outcomes: describe the components needed for transcription in bacterial cells, describe mechanisms for transcriptional activation and repression in bacteria. Identify the structural characteristics of some bacterial dna-binding proteins. Transcription: the process in which genetic information encoded in dna is copied into rna by. Consensus sequence: the most frequent base at each position in a group of functionally related. Bacterial transcription terminology: promoter: the dna sequence required to start transcription of a gene or operon; tells. Rna polymerase to start transcription: terminator: the dna sequence required to stop transcription; tell rna polymerase to stop transcription. Bacterial transcription: operon: a set of genes transcribed under the control of an operator gene. Genes under an operon are either all off or all on at the same time. In humans, each gene is typically transcribed into its own mrna. In bacteria, multiple genes get transcribed onto 1 mrna.
