Chapter 13: Regulation of Gene Activity

Learning Outcomes

13.1 Prokaryotic Regulation

1. Describe the structure of an operon and state the role of each component of the operon.
2. Explain how the trp and lac operons of prokaryotes are regulated.
3. Distinguish between positive and negative regulation of gene expression in prokaryotes.

13.2 Eukaryotic Regulation

1. List the levels of control of gene expression in eukaryotes.
2. Summarize how chromatin structure may be involved in regulation of gene expression in eukaryotes.
3. Identify the mechanisms of transcriptional, posttranscriptional, and translational control of gene expression.

13.3 Gene Mutations

1. Distinguish between spontaneous and induced mutations.
2. Identify how mutations influence protein structure.
3. Summarize how mutations may cause cancer.
