Chapter Questions
What is the difference between gene expression and gene regulation?
What is meant by different "levels" of gene regulation?
How can DNA bases and chromatin can be modified to regulate gene expression? Does this modification result in increased or decreased gene expression?
How does $X$ -inactivation in female mammals result in patchy coat colors in calico cats?
How can one protein-coding gene code for more than one polypeptide chain?
How do small regulatory RNAs differ from mRNA?
What are three ways in which gene expression can be influenced after mRNA is processed and leaves the nucleus?
How can the binding of a molecule as small as a single amino acid change the ability of a large, multi-subunit protein molecule to bind a specific DNA sequence?
What would be the consequence of a mutation in the lacI repressor gene that produces repressor protein that is able to bind to the operator but is not able to bind allolactose?
What is the role of the CRP-cAMP complex in positive regulation of the lactose operon in $E$. coli?
How are the lytic and lysogenic pathways regulated?
