Summary Introduction
In transduction, the bacteriophage (a bacterial virus) transfers DNA molecule from one cell to another cell. The transduction is classified into two methods, namely, generalized transduction and specialized transduction. In generalized transduction, any donor gene can be transferred to the recipient cell and that lead to forming a transductant.

2) it enables the bacteriophage to take over the cell.
O 3) it speeds up the viral infection cycle.
4) it allows the bacteriophage to infect cells it would not normally infect.

generations of infected cells.
