Understanding Transduction in Bacteria: The Mechanism for Gene Transfer, Evolution and Antibiotic Resistance

transduction

converting stimulus in the environment into neural signals

Transduction is the process of transferring genetic material from one bacterium to another using bacteriophages (viruses that infect bacteria). During transduction, a bacteriophage infects a bacterium and takes over its cellular machinery to produce new phage particles. However, during this process, some of the bacterial DNA is mistakenly packaged into the newly produced phage particles instead of the phage DNA.

If the phage particle containing the bacterial DNA infects another bacterium, it can inject this DNA into the new host cell. Once inside the new bacterium, the foreign DNA can be integrated into the bacterial chromosome through the process of recombination.

Transduction can occur between bacteria of the same or different species, and it can transfer a wide variety of genes including antibiotic resistance genes, virulence factors, and metabolic pathways. It is an important mechanism for bacterial evolution and the spread of antibiotic resistance in bacterial populations.
