What Is Generalized Transduction?

In generalized transduction, a bacterial gene is passed through bacteriophage to a new bacterium while carrying bacterial DNA without a viral DNA, according to Biologyexams4u.com. This process is enabled by lytic phages that allow DNA segments to be relocated by the virus without combining the part to bacterial chromosome.

Part of the benefactor bacterial DNA is unintentionally enclosed in a capsid. Additional infection of the virus and lysis of the particle to the new bacterium makes recombination between homologous parts of the recipient chromosome and injected DNA to occur and form a rDNA after the release of the donor material. According to National Center for Biotechnology Information, only a few number of phage progeny are able to transport donor genes in the process of generalized transduction.
