GEN-3000 Final: GEN-3000 :
Document Summary
Exam 5 study guide updated: gene expression (ch 15, negative vs. Inducible: production is on when inducer is present: repressible: production is off when a product is present, prokaryotic, operon structure: single transcriptional unit, contains series of genes, a promoter, and an operator. In prokaryotes, genes are often set up in an operon. Now we only have to regulate this one place. If transcription stops, we do not get to the structural genes (happens when tryptophan levels are high). Rna interference is a process in which the introduction of dsrna into a cell causes specific degradation of mrnas containing the same sequence: mrna level of control, transcriptional activator proteins, bind to dna in regulatory promoter. Interact with other components: rna silencing, enhancers and silencers alter transcription at a distant promoter. Americans: cancer: is known as a genetic disease, it is not necessarily inherited. It kills on in every 5: benign: tumor remain localized.
