As the levels of CI increase, more regions of the operator can be bound. CI is not produced when all regions are bound. If no regions of the operator are bound with protein, the lytic cycle can be entered. Upon entering the lytic cycle, the Cro protein is used. With Cro bound, no repressor will bind here and the lytic genes will be transcribed and the lytic cycle will proceed.
Transduction is an important means of creating genetic diversity in bacteria.
It allows gene transfer between members of the same species and between members of non-related species. Unlike it's counterparts, transformation and conjugation, it provides protection for the DNA in the form of the viral capsid. This allows the DNA to exist longer outside the bacterial cell where it can come into contact with cells that are not necessarily in close proximity when the phages are released.
