Unformatted text preview: Corepressor substance activates the repressor, which then binds to the operator and turns the structural genes "off" Positive Control: cAMP Receptor Protein (CRP) No Control: Some operators have no repressors (genes expressed at a constant rate) Eucaryotic Genome Organization How is the genome structured? Eucaryotic Gene Expression: Chromosomal Level: DNA packing: DNA methylation: Gene Amplification: Transcriptional Level : Enhancers Transcription Factors Post-Transcriptional Level: mRNA processing: Regulation of mRNA degradation: Transcription level: Post-Translational level: cleavage and modification transport and degradation:...
