Transduction is the process of transferring genetic information from one cell to another at certain intervals. Unlike DNA replication, which creates an exact copy of the original DNA, transduction occurs through extracellular DNA molecules (DNA from viruses or bacteria), which can be integrated into the genome of the host cell and can transfer genetic information not only from cell to cell, but also from species to species.
In living organisms, transduction is an important function for the transmission of genetic changes that occur as a result of mutations or natural selection. It can also be used for medical purposes, such as cancer therapy using transducer cells containing genes that can kill cancer cells.
However, in addition to beneficial applications, transduction can also have negative consequences in the event of contact with pathogenic microorganisms, such as viruses or bacteria. This can lead to cell invasion and infection of the body.
There are two main types of transduction: obligate and optional (nonspecific). Obligate transduction is necessary for genome organization in a cell. All representatives of the genus have the same picture of the genetic apparatus; each virus has single-stranded linear repeats of genes that carry
