Choose the statements that best describe how riboswitches regulate gene expression. They act as recruitment sites for ribosomes when not bound by a repressor. They act as ribozymes, inducing self-cleavage of the mRNA. They act as corepressors, binding repressor proteins to prevent transcription. They bind to complementary mRNA strands to prevent translation. They form a secondary structure in mRNA that changes conformation when bound by regulatory proteins.

-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)
