Questions and Answers

Which of the following is true about F+ and F- in conjugation?

F+ is the receiver and becomes F-, while F- is the donor and contains the F factor

F+ and F- are both donors and contain the F factor

F+ is the donor and contains the F factor, while F- is the receiver and becomes F+ (correct)

F+ and F- are both receivers and become F+

What is the difference between F' and transduction?

F' is a type of transduction that involves the transfer of F and chromosomal DNA

F' is a mechanism similar to transduction, but it is not transduction

F' is the imprecise excision of an F factor from an Hfr, resulting in the transfer of extra genes (correct)

F' is a type of specialized transduction that only involves the transfer of F factor

What is hFR in conjugation?

hFR is the integration of chromosomal DNA with an F factor

hFR is the conjugation of chromosomal DNA with an F factor (correct)

hFR is a type of transduction that involves the transfer of Hfr DNA

hFR is a type of specialized transduction that only involves the transfer of F factor
