Conjugation
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.
Bacteria form a structure called a pilus during conjugation to exchange genetic information. The pilus helps in the transfer of DNA between two bacterial cells.
Transduction
This process is called bacterial conjugation. It involves the transfer of genetic material, such as plasmids, between bacteria through a tube-like structure called a pilus. This allows for the exchange of genes that can confer traits like antibiotic resistance or virulence.
The process is called conjugation. It involves the transfer of genetic material, usually in the form of plasmids, from one bacterium to another through a tube-like connection called a pilus. This allows for the exchange of beneficial traits, such as antibiotic resistance genes, between bacteria.
Conjugation
Pilus, plasmid
A tubular appendage found on some bacteria that allows transfer of DNA between bacterial cells is called a pilus. Pili are composed of protein subunits and serve as a bridge for the transfer of genetic material during a process called conjugation. This enables bacteria to exchange DNA and acquire new genetic traits.

Bacteria are known to have a high DNA transfer capability through a process called conjugation. During conjugation, they can transfer a significant amount of DNA to another bacterium by forming a physical bridge between cells through a structure called a pilus. This allows for the transfer of plasmids or other genetic material between bacteria.
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.

Prokaryotes have additional ways to evolve their genomes besides relying on relatively infrequent mutations. Through genetic recombination, individual prokaryotic cells can share DNA with other individual cells, not necessarily belonging to the same species.They can also exchange genetic material by transformation, transduction, and conjugation.In conjugation, plasmid DNA is transferred from cell to cell using something called a sex pilus. In transformation cells pick up DNA from their environment. Lastly, transduction is the transfer of genetic material from one cell to another using a virus.
A self-transmissible plasmid is a type of plasmid that can transfer genetic material from one bacterium to another through a process called conjugation. This plasmid carries the necessary genes for forming a conjugative pilus and transferring the plasmid DNA. Self-transmissible plasmids play a significant role in horizontal gene transfer among bacteria.
