Q. The diagram is given below shows conjugation between F + or Hfr donor cells with F-recipient cells. On the basis of this diagram, answer the following questions.1. How you will differentiate between an F + and an Hfr strain? 2. Among two strains, which type of strain do you expect to transfer bacterial genes to F-cells? 3. What may be the end status of both donor and recipient cells of F plasmid-mediated conjugation? 4. What may be the end result when Hfr conjugates with F- cell?
