How does the bacteria use this system to efficiently control the production of the lacZ protein?
Part 1 – Simulating how Gene Expression works Open the simulation from https://phet.colorado.edu/en/simulation/legacy/gene-machine-lac-operon On the screen you should see two floating blue molecules, these are RNA polymerase. There is also an incomplete DNA gene beneath them. You can turn on the legend in the lower right and that will help you identify the molecules. Click […]
