Transduction

Transduction is the process of transferring genetic information between bacteria, which is carried out indirectly by a bacteriophage (phage). As a result of transduction, the phage transfers part of the DNA from one bacterium to another, which can lead to changes in the genetic composition of the bacteria.

The main mechanism of transduction is the integration of part of the bacterial DNA into the phage genome during its replication. When a phage infects a bacterium, it injects its DNA inside the bacterial cell, at which point transduction can occur. Some of the bacterial DNA binds to the phage and when the host bacterium is destroyed, the phage infects another bacterium and transfers DNA from the previous host to it.

It is important to note that transduction can only occur between bacteria of the same species that are capable of recombining genetic material. In addition, not all bacteriophages are capable of transduction, since to do this they need to include DNA sections of the bacteria that they infect into their genome.

Transduction is of great importance in genetic research and can be used to create new strains of bacteria with desirable properties. However, this process can also lead to the spread of genetic defects and increased bacterial resistance to antibiotics.

In general, transduction is an important mechanism for the transfer of genetic information between bacteria, which can lead to the emergence of new strains of bacteria with altered properties. However, this process can also have negative consequences, so it is important to carefully monitor its effects on living organisms.

Transduction is the process of transferring genetic information between bacteria, which occurs with the help of phages. In this process, phages use their DNA to transfer genes from one host to another.

How does transduction occur?

Phages are viruses that can infect bacteria and other organisms. When a phage infects a bacterium, it enters the cell and begins to multiply. As a phage reproduces, its DNA can combine with the DNA of a bacterium.

When a phage replicates inside a bacterium, it can transfer its DNA to other bacteria that are nearby. If another bacterium is infected with the same phage, the phage's DNA can combine with its own DNA.

Thus, genes are transferred from one host to another using phage. This process is called transduction.

Why is transduction needed?

Transduction plays an important role in bacterial genetics. It allows you to study the genetic characteristics of different strains of bacteria and identify mutations that lead to changes in the properties of bacteria.

In addition, transduction is used in genetic engineering to create new strains of bacteria with desired properties. For example, transduction can be used to transfer antibiotic resistance genes from one bacterium to another to create a strain that is resistant to those antibiotics.

Conclusion

Transduction is an important process that allows you to study the genetics of bacteria and create new strains with desired properties. Thanks to transduction, we can better understand how genes work and how they influence the properties of bacteria.

In modern biotechnology, the concept of “transduction” is widespread, which means the process of transferring genetic information from a bacterium of one species to a bacterium of another species using a phage, which makes it possible to overcome the interspecies barrier in the selection of bacteria and cellular engineering of organisms cultivated in laboratory conditions. Viruses can transfer fragments of their genome into various organisms, but only phages are capable of transferring genetic material between bacteria. Transduction is the main mechanism of genetic engineering of bacteriophages, without which it would be very difficult to modify bacteria using engineering gene transformation methods.
