  21. rII region of phage T4 T4 rII+ T4 rII - T4 DNA T4 DNA rII rII rIIA rIIB rIIA- rIIB

  22. Distinguishing T4 rII+from rII- T4 rII+T4 rII - T4 rII+T4 rII - E. coli B x E. coli K() x T4 rII - cannot grow on E. coli K()

  23. Why is T4rII-defective? T4 rII -  E. coli K() No infection T4 rII+  Lysis E. coli K()
