Lac Operon: Advanced Look

The lac Operon is composed of several different processes and behaviors. In order to accommodate the larger number of stills contained in Advanced Look, the selected images have been grouped into pages that correspond with these different areas.

To see the Flash movie for the following sequences of images, click here.

The repressor and its position in the lac operon system are explained. More detail...
The lac genes are transcribed and translated into functional proteins.   More detail...
The proteins encoded by the lac genes become fully functional. More detail...
 
The lactose concentration is reduced and leads to shutdown.   More detail...
