# Bacterial conjugation is the transfer of genetic material between two bacterial cells by direct contact or by bridge like connection between two cells made up of pili. One acts as a donor and another acts as an acceptor. This is considered as sexual reproduction or mating of bacteria becuase, genetic material is getting exchanged among two bacterial cells.
It is a mechanism of horizontal gene transfer. Mostly the exchanged material would be plasmid or transposons.
For this process formation of pilus is more important. secondly relaxase enzyme which creates a nick in one of the strands of the conjugative plasmid. A Hfr cell and an F cell are needed.

Which of the following is NOT true about bacterial conjugation An F factor drives replication and transfer of a conjugative plasmid The genome of the bacterial chromosome in the donor cells is altered through ectopic recombination Transfer is mediated by a tube-like pilus formed between the adjacent cells Mating cells often break apart before transfer of the entire bacterial chromosome. The transferred DNA can be incorporated in the recipient cell bacterial chromosome via homologous recombination.

Illustrate a conjugation event with an F’ cell that is lacIS lacP+lacO+lacZ- lacY-on the bacterial chromosome and lacI- lacP+ lacOC lacZ+ lacY+ on an F plasmid with an F-cell that is lacI+ lacP+ lacO+ lacZ+ lacY-. Draw both cells before the conjugation event, as well as the recipient cell after conjugation occurs. Underneath all three cells, note whether the production of permease and beta-galactosidase would be high, basal, or none, and describe HOW the proteins and DNA sequences interact to...

13. Which of the following statements about conjugation is false? A) Conjugation is sexual reproduction for bacteria B) In conjugation a bacterium carries a fertility plasmid. C) In conjugation a bacterium forms a small hollow tube called a pilus. D) In conjugation a bacterium attaches to a neighboring bacterial cell that lacks a fertility plasmid. E) Conjugation can be a problem because fertility plasmids often carry genes that endow cells with drug resistance or the ability to produce toxins.
