Conjugation
When genes transfer the tra gene nicks the DNA at its origin of transfer creating a pilus so the chromosome (which contains the gene) can transfer to the other DNA.
conjugation occurs between two bacterial cells and transfers DNA in the form of plasmids. this is one way to transfer of genetic material - it is not sexual reproduction, The other two ways to transfer genetic material between bacteria are transformation and transduction. In order to be able to perform coagulation (transfer of a plasmid) the bacteria must have an F factor (DNA that codes for the PILI protein, which allows the bacteria to create a bridge through which the bacteria inject the plasmid to another bacteria). Bacteria with F factor is called F+, and without it is called F-. F+ can transfer the plasmid to an F- bacteria.
Transduction
The three forms of bacterial DNA exchange are (1) TRANSFORMATION, (2) CONJUGATION and (3) TRANSDUCTION.

When plasmids, are used to transfer foreign DNA to other cells the plasmid is called a
Transcription
Bacteria with the F plasmid (free or integrated) make pili (singular pilus, sometimes referred to as the sex pilus) to connect with bacteria that do not have the F plasmid to initiate DNA transfer. However, the pili are actually used as a harpoon to reel in the other bacteria so that physical contact between the membranes of the bacteria could be made. DNA is only transferred after the fusion of the cell membranes. It is also a common misconception to think that bacterial conjugation is like 'sex' since it does not involve recombination of genes or cycles of haploidy and diploidy.
It is called Transduction.
