1. The problem statement, all variables and given/known data Compare and contrast the transfer of the F factor and the lambda phage during conjugation under the following conditions: a) Hfr([tex]\lambda[/tex]) x F- b) Hfr x F- ([tex]\lambda[/tex]) c) Hfr([tex]\lambda[/tex]) x F-([tex]\lambda[/tex]) 3. The attempt at a solution a) Hfr infects F- which is non-immune --> lysis occurs c) Hfr tries to infect F- with lambda already inserted: immune---> no lysis The transfer where F- already has lambda inserted I'm not sure of what happens. The other two are textbook. My guess would be that Hfr infects F- and excises phage lambda out of the F- which would be non-immune but I don't think lysis would occur. Any help or guidance would be appreciated.
