At high salt concentrations, the mRNA containing poly(A) tails binds to the complementary oligo(dT) molecules of the affinity column, and so, mRNA will be retained; all other RNA molecules can be washed through the column by further high salt solution. finally, the bound mRNA can be eluted by using

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?
