Explain how a gene may be repressed or induced. Use terminology that includes the following: promoter, structural genes, operator, operon, regulatory gene, repressor protein, inducer, co-repressor. How does osmotic pressure affect non-halophilic, halotolerant, and halophilic bacteria? What are the chemical requirements for growth (both macro- and micro-elements), and how do different organisms acquire these chemicals?

-Explain how gene expression is controlled -Describe the difference in control of gene expression between eukaryotes and prokaryotes. -Explain how regulatory proteins (activators, repressors) work -Describe the parts of the DNA involved in regulation (promoter and enhancer regions) -Contrast control of gene expression by repression with control by induction Identify the mechanisms for gene expression control in the lac and trp operons. -Explain what transcription factors and regulatory proteins are and how they regulate gene expression in eukaryotes. -Describe how chromatin structure (DNA methylation and histone modification) can affect gene expression -Explain the process of protein degradation and its purpose -Contrast the mechanisms regulating gene expression depending on when they act on: 1) regulating transcription, 2) posttranscriptionally (regulating the mRNA and protein synthesis) and posttranslationally (regulation of protein degradation)
