Lecture Material

the virtual lactose operon

Are you "Plugged-In?"
Most of the materials within this site were created using Macromedia Flash, which provides for swift downloads, smooth animation, and interactivity. For it to work, however, you must have the Flash Plug-In installed on this machine. You can test whether or not the plugin is correctly installed by using our FlashTest page. If you have the plugin, you should see a simple image created with Flash. If you do not, you should be automatically redirected to the Macromedia Download site, where you can download and install the plugin by following the directions provided.

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.
