Lac Operon Overview Tutorial
Take an interactive trip through the Lactose Operon. Get to know the molecules -- what they do, who they interact with, and
see them in action!
Single Copy Mutant Scenarios
This tutorial presents situations when mutations are present in key players in lac regulation.
Answer questions and test yourself throughout the tutorial. We may or may not cover these individual mutations in lecture,
but based on what we do cover in class, there's nothing in here that you wouldn't be expected to
figure out on an exam.
Merodiploid Mutant Scenarios
What happens to lac regulation when a second copy of some or all of the genes in the
lac operon are added to the cell? Find out by reviewing 5 such situations, and test yourself
as you work your way through these tutorials. Most of this is a bit beyond what you would be expected to know for an MCB
150 exam, but the material may help you.
