The process of taking the free fragments of DNA by bacteria from the surrounding medium is known as transformation. Only the competent bacterial cells can take up DNA by transformation. Limited types of bacteria can undergo transformation naturally such as Bacillus, Streptococcus, Neisseria, Haemophilus, … See more The process that exchanges genetic information between two bacteria through a direct cell-to-cell contact is known as conjugation. It is mediated by conjugative plasmids that are encoded with efficient mechanisms for the … See more The process of transferring bacterial DNA from one cell to another cell by means of bacteria-infecting viruses is known as transduction. It is considered as an efficient method of DNA transfer since foreign DNA is … See more The exchange of genetic material between DNA occur in three methods; conjugation, transformation, and transduction. Conjugation is the direct transfer of genetic material between two bacteria with the help of a sex … See more WebThe genetic information for making a pilus is called the F (fertility) factor. The donor bacterium, which is considered F+, makes a copy of the plasmid and extends the pilus to the recipient (the F- cell). The newly copied plasmid is then transferred to the recipient. In the end, both the donor and the recipient bacteria have a copy.
