Question

What usually happens to the recipient cell following conjugation with an Hfr cell?

The recipient cell becomes an Hfr cell.
The recipient cell may become either an F+ or an Hfr cell.
The recipient cell remains an F+ cell.
The recipient cell remains an F- cell.

Answer 1

The recipient cell may become either an F+ or an Hfr cell following conjugation with an Hfr cell.

Step-by-step explanation:

Following conjugation with an Hfr cell, the recipient cell may become either an F+ or an Hfr cell.

An Hfr cell is created when the F plasmid integrates into the bacterial chromosome through recombination. This results in the recipient cell becoming an Hfr cell and having a high frequency of recombination. On the other hand, the recipient cell can also become an F+ cell if one of the semi-conservatively replicated F plasmids remains in the donor cell and another is transferred to the recipient cell.
