  1. Lecture 9: Bacterial genetics

  2. Exam 1 results Exam 1 average: 79.4

  3. Bacteria and bacteriophages E. Coli Bacteriophages

  4. Bacterial growth

  5. Selecting for bacterial mutants a mutation that confers antibiotic resistance a mutation in the ability to utilize a carbon source

  6. Genetic recombination in bacteria Bacterial chromosome

  7. Gene transfer in bacteria

  8. Discovery of bacterial conjugation

  9. Cell-cell contact is required for conjugation

  10. Transfer of F factor during conjugation pilus

  11. In Hfr bacteria F factor integrates into the bacterial chromosome

  12. Recombination following conjugation with an Hfr strain

  13. Interrupted mating experiment

  14. Linear gene transfer during conjugation with Hfr donor Recombination can occur between A—B segment from Hfr and the a—b region on recipient chromosome

  15. The origin determines the order of gene transfer during conjugation

  16. A single crossover integrates F factor into the chromosome Insertion sequences
