Gene recombination may also be possible when parts of the genome are moved from one cell to another with bacteriophagus. It's called traction (transport). For the first time in 1951, it was shown that bacteriophagus, multiplying in the strain of cinebacteria diphtheria forming toxin, could transfer this characteristic to the non-toxicated strain of diphtheria injectors. The trajectory mechanism has now been examined in some detail. It is related to the presence of a moderate (non-viral) phase in the bacterial cell. In such leased crops, temperate bacteria is included in the genetic apparatus of the cell and can be transmitted indefinitely to the progeny of the bacteria when multiplying. Due to various reasons, such as ultraviolet radiation, moderate phases may come out of bacteria chromosomes in cytoplasm and remove different genomes from its genome. In the cytoplastics of bacteria, becoming virulent, phases start to breed and destroy the microbial cage. When the new bacterial cells are hit, the phases are reintroduced into their chromosome and new genes are added to it. These genes in the cage give rise to new signs at the bacteria, which is the original donor bacteria.
There is a general transmission in which phases, including in any chromosome area, are transferred to the recipient cage to various genes controlling the variety of bacteria-donor properties. With a specific transduction, moderate phases are constantly located in a certain place of chromosome. Therefore, they carry only a certain gene located next to the project. In an abortion transduction, bacterial DNA fragments, captured by phases, penetrated into a recipient cell, operate in a cell cytoplastic, not including in her genome. When the bacteria is divided, it only passes one daughter's cage.
