After conjugation between an F+ cell and an F- cell, does the F- cell remain as F- or does it become F+? After

conjugation between an Hfr cell and an F- cell, does the F- cell remain as F- or does it become F+? Explain each answer.



What will be an ideal response?


ANSWER: After conjugation between F+ and F- cells, the F- cell becomes F+ because the F factor is
completely transferred from the F+ cell to the F- cell. After conjugation between Hfr and Fcells,
the F factor is not completely transferred, and therefore the F- cell remains F-.
