The diagram below shows the F factor and a portion of the E. coli chromosome that has three different insertion sequences (IS) of the same type as is carried on F.

                     

Describe the three different Hfrs (Hfr #1, Hfr #2 and Hfr #3) that can be formed by recombination between the IS on F and each of the IS sequences on the chromosome. Some including the positions of each of the markers (A, B, C, and D) and state which of these markers would be transferred early?

The pathway for polypeptides exported from E. coli includes the following steps, which occur in what order for correct export?

1.  A chaperone, SecA, binds to the polypeptide.

2.  A chaperone, SecB, binds to the polypeptide.

3.  ATP is hydrolyzed by Sec A.

4.  SecA pushes 20 amino acids of the polypeptide into the translocation complex.
