A fluctuation test was carried out to determine the rate of mutation to Azetidine resistance (a toxic proline analog) in S. typhimurium. Twenty tubes of rich medium were each inoculated with a few wild-type cells and the cultures were grown to 10° cells / ml. A 0.1 ml sample of each culture was then plated on each plate (a total of 20 plates) to detect AztR mutants. The results are shown in the following table. Calculate the mutation rate of S. typhimurium to AztR. Culture # EAztR mutants Culture # AztR mutants 0. 11 2. 12 13 4. 4. 30 14 15 303 97 69 14 16 17 18 19 20 9. 10 19

An interrupted mating study is carried out on Hfr strains 1, 2, and 3. After conjugation is established, a small sample of the mixture is collected every minute for 20 minutes to determine the distance between the genes on the chromosome. Times of entry for each of the three Hfr strains studied in the interrupted mating are provided in parenthesis. The total duration of conjugation (in minutes) is given for each transferred gene.

Explain the process of how X-gal screening works with pUC19, you may build a model with boxes and arrows. 2. You are utilizing BamHI (GGATCC) restriction site and HindIII (AAGCTT) restriction site. Within pUC19, BamHI is at position 263, while HindIII is at position 233. (Hint: position is like coordinate on a map). If you manage to insert GTF2H5 in pUC19 vector, what are the sizes of fragments if you digest the pUC19-GTF2H5 (this is after insertion) with the following restriction enzyme combination after gel electrophoresis: BamHI and HindIII There is an NdeI site right in the middle of the GTF2H5 that has been inserted in pUC19, what would be the fragment sizes, if you digest with BamHI and NdeI. HindIII and NdeI BamHI, HindIII, and NdeI. 3. Design an experiment to confirm the presence of insert GTF2H5 in pUC19 vector using the following method (besides restriction analysis above), assuming that you know the sequence of GTF2H5: Southern Blot Polymerase Chain Reaction
