Multiple Cell Behavior
Complete the worksheet.
1. Visit the PHET Interactive Simulations website from the University of Colorado Boulder.
2. Click "Multiple Cells."
3. Click on "Show Real Cells" to read about the cells that you are examining in the simulation. On the start screen of the simulation, you are shown a single E. coli cell that has green fluorescent protein (GFP) added to its genome so that it causes the cell to glow green when presented with ultraviolet light.
4. Observe the single cell for at least 30 seconds.
What do you notice about the color of the cell and how it changes?
5. Drag the slider on the bottom of the screen from "One" to "Many."
What do you notice about the color of the cell sand how they change?
What do you think might cause the cells to appear different?
6. Open the three menus on the right (Concentration, Affinities, Degradation by clicking the "+" signs.
7. By maximizing the production of GFP, we can cause the cells to glow greener. See what variables might impact the production of GFP. How can you change the following variables to maximize the production and expression of GFP?
|
Concentration of Positive Transcription Factor
|
|
|
Concentration of mRNA Destroyer
|
|
|
Affinity for Positive Transcription Factor
|
|
|
Affinity for Polymerase
|
|
|
Protein Degradation
|

8. Consider your readings from this week about bacteria and viruses.
How do your observations relate to the readings from this week?
