gene expression involving multiple operons. Give an example of
cascade regulation and use this example to explain its basic
principle.

Summarized Chapter 17 Gene expression: From Gene to Protein and
Chapter 18 Regulation of Gene Expression. What they were about? Why
they are important? And how they link to other chapters, at least
1/2 page in length for both chapters.
Explain the regulation of gene expression in eukaryotic
cells.
Discuss mechanisms by which gene expression may be
altered.
How do these alterations induce cancer-causing mutations in
cell DNA?
Explain how cancer is formed.
Describe genetic changes found in cancer cells and how these
changes lead to alterations in cell behavior.
Determine whether proteome data can be utilized in genetic
disorder diagnosis.
Relate the Human Genome Project data to the analysis of cancer
genes.
Give two examples of inducible/repressible gene
expression. Explain the function of the genes, the mechanism of the
regulation, and why it is important to have a way to control the
level of gene expression.
Bacterial operons & regulating metabolic
pathways
Two kinds of control: enzyme regulation vs. gene regulation.
Why?
trp operon. How does the presence of tryptophan prevent the
synthesis of more tryptophan (2 different ways)?
lac operon. Compare & contrast with trp.
Why are operons for catabolic and anabolic pathways regulated
differently?
Positive vs. negative gene regulation. Why would both be used
for the same operon?
AraC mechanism. Is AraC an inducer or a repressor?
Give two examples about inducible/repressible gene
expression. Explain the function of the genes, the mechanism of the
regulation, and why it is important to have a way to control the
level of gene expression.
