Strain I Tet C Van P Strain II Plain agar Agar + Amp Agar +Tet Agar + Van Agar + Van + Tet Agar + Van+ Amp Agar +Tet+ Amp Amp Strains I and II are plated on "confirmation" plates. Fill in the table with a+or-according to whether you think the bacteria will grown on the plate (+) or not (-). Strain I Tet = tetracycline Van vancomycin Amp = ampicillin Strain II C= chromosome P = plasmid r = resistance

2. Strains I and II undergo conjugation and colonies from the "mating" plate are put on the following agar plates with antibiotics. Look at the results in the following table: Plain agar Agar + Amp Agar + Tet Agar + Van Agar + Van + Tet Agar + Van+ Amp Agar + Tet+ Amp Strain III + + + a. b. c. Which strain is the donor? Stain 2 is the donor Which strain is the recipient?___stain 1_ What genetic information was donated (plasmid, chromosome or both) chromosome d. Draw the genetic makeup of the recombinant Strain III Amp r Str r
