Suppose you set up a F+ x F- conjugation experiment (a "mating").
The F+ cell is lac+ meaning it has all wild type genes for lactose utilization. This is the "donor" cell.
The F- cell is lac- because it has a mutation in its promoter sequence that prevents RNA
polymerase from binding. This is the "recipient" cell.
You allow sufficient time for completion of conjugation.
After conjugation, the donor cell is now F+ and lac+
v and the recipient cell is
F+ and lac+
now
Answer choices:
Hfr and lac+
F+ and lac-
F+ and lac+
Hfr and lac-
