1) Generalized transduction


                    In this type of transduction the virus adsorb to the host (bacteria) cell wall and inject its nucleic acid or DNA into the bacterial cell or cytoplasm. These DNA  produce enzyme in host cell which cause the host cell’s DNA to break into many fragments and directs the host metabolism to produce more virus DNA and its protein coats. After sometime the DNA of virus and the protein assemble to form a new viruses .During this assembling some of the small pieces of chromosome of bacteria get arranged in the chromosome of virus . During subsequent breakdown of bacterial cell the new viruses are released. The released virus when infect a new bacteria, it transfer not only its gene but also the genes of bacteria . This type of transduction is known as Generalized transduction.
