Question #1 Check all that apply.
The bacterium E. coli can take up the disaccharide lactose from its environment and can use it as an energy source. Once it is inside the cell, the lactose molecule can also bind to a protein that binds the bacterium's DNA at a particular DNA sequence. Which of the following cell structures MUST lactose go through before it can bind to the DNA-binding protein? Please choose all correct answers.

1)Lactose can move directly through the plasma membrane into the cell.

2)Lactose moves through a plasma membrane transport protein to enter the cell.

3)Lactose diffuses through the cell's cytoplasm.

4)Lactose moves through the cell's lysosome.

5)Lactose must be transported across the nuclear membrane through a nuclear pore.

6)Lactose moves into the nucleus directly through the nuclear membrane.
