Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. [1] This takes place through a pilus. [2] [full citation needed] It is a parasexual mode of reproduction in bacteria. Escherichia coli conjugating using F-pili. These long and robust ...
Despite being integrated into the chromosomal DNA of the bacteria, the F factor of Hfr cells can still initiate conjugative transfer, without being excised from the bacterial chromosome first. Due to the F factor's inherent tendency to transfer itself during conjugation, the rest of the bacterial genome is dragged along with it.
Sexduction is not the same as Conjugation why when you search for sexduction it redirects to conjugation. sexduction is another proccess in bacteria resulting F-prime factor. It happens when an abnormal crossing over occures in Integrated F-Factor in genome resulting a F-factor with additional genes called F-prime factor
Following a sabbatical working with Francois Jacob at the Pasteur Institute in 1956-57, Adelberg discovered the phenomenon known variously as “F-mediated transduction,” “F-duction,” and sexduction, which consists of the transfer through recombination of chromosomal fragments by the sex factor (F) during bacterial conjugation. [15]
Bacterial recombination is a type of genetic recombination in bacteria characterized by DNA transfer from one organism called donor to another organism as recipient. This process occurs in three main ways: Transformation, the uptake of exogenous DNA from the surrounding environment. Transduction, the virus-mediated transfer of DNA between bacteria.

Griffith's experiment discovering the "transforming principle" in Streptococcus pneumoniae (pneumococcal) bacteria. Griffith's experiment, [1] performed by Frederick Griffith and reported in 1928, [2] was the first experiment suggesting that bacteria are capable of transferring genetic information through a process known as transformation.
