Final answer:
Integration of the F+ state into the bacterial chromosome occurs through recombination, resulting in the formation of an Hfr cell. The Hfr cell can transfer chromosomal DNA to recipient cells during conjugation.
Step-by-step explanation:
Integration of the F+ state into the bacterial chromosome occurs by integrating the F plasmid into the chromosome through recombination, resulting in the formation of an Hfr cell. The Hfr cell has the ability to transfer chromosomal DNA to recipient F- cells during conjugation.
During conjugation, the F plasmid is transferred through a conjugation tube formed between the Hfr cell and an F- cell. One strand of the bacterial chromosomal DNA is nicked at the original insertion site of the F plasmid, allowing the transfer of chromosomal DNA to the recipient cell. The transferred DNA can be either integrated into the recipient cell's chromosome or maintained as part of the F' plasmid.
