Bacterial Conjugation

Does anyone know this: After an Hfr transfers its F Hfr to an F-, is the F- become an Hfr, not an F+? thanks in advance

@ScarofKenshin If the F plasmid, containing a replication origin and genes that promote transfer to other cells, excises itself from the Hfr cell ( reverses integration process) then it will become an F+ cell in a single recombination event. This is conveniently called excision. Excision can be inaccurate, meaning the F plasmid picks up chromosomal DNA in the process of excision. This creates an F' cell, which can easily transfer into other cells such as an F- cell. resultant = partial diploid
