WebSep 26, 2024 · Bacteriophages, also known as phages, are viruses that infect and replicate only in bacterial cells. They are ubiquitous in the environment and are recognized as the most abundant biological agent on earth. They are extremely diverse in size, morphology, and genomic organization [1][2][3]. However, all consist of a nucleic acid genome encased … WebIn conjugation, genetic material is exchanged during a temporary union between two cells, which may entail the transfer of a plasmid or transposon. In transduction, DNA is transmitted from one cell to another via a bacteriophage.

WebIn another case, viruses play a role in genetic exchange between bacteria. Bacterial viruses, or bacteriophages (sometimes just called “phages”) ordinarily attach themselves to bacterial cells and then inject their genetic material into the cells. Such viruses hijack bacteria, using bacterial cell components to generate new phage particles.
