BIOL 2081C Lecture Notes - Lecture 21: Corepressor, Trp Operon, Tryptophan Synthase
Document Summary
Instead complete online assignment #3 using online databases to. In addition to the basic steps of dna transcription and mrna translation into protein, you must also understand the pre-transcriptional and post-transcriptional mechanisms that regulate which mrnas are made, which are translated, and which will be degraded. Controlling rna levels is also a common experimental technique used to manipulate phenotype in a cell culture system or an animal model. We discuss these concepts today and during the next class. Watch: mr. anderson discuss the fundamentals of gene expression. This activated repressor now binds to the operator site and prevents the binding of rna polymerase, thereby inhibiting the protein synthesis. Therefore, trp repressor needs the presence of a corepressor to be active and is inactive by itself. After you do the reading, complete the los on your own. During class, we will work through the los and some more challenging gene regulation problems.
