what do expect to see when you treat E coli with 3M HCI
Homework Answers
Option b is correct: turbidity will be less than the control group.
Explanation: 3M HCl will cause the death of E.coli cells. As the death occurs they will precipitate a t the bottom of the tube and as a result the turbidity will be low than the control.

1. On which plate(s) would you expect to find bacteria most like the E. coli on the source plate? Explain. 2. On which plate(s) would you find only genetically transformed bacterial cells? Why? 3. What is the purpose of the control plates? Explain the difference between the controls and why each one is necessary. 4. Why would one compare the -DNA/+Amp and DNA/+Amp plates?

The gene machine program shows you what happens when lactose is present in E. coli, and how the lac operon is under negative control. However, the lac operon is also under positive control from a protein called CRP, eAMP Receptor Protein. The absence of the lac repressor is essential but not sufficient for effective transcription of the lac operon. RNA polymerase also depends on the presence of CRP. Like the lac repressor, which can bind to the DNA and lactose....
