These unique features and other features gave significance of the T-even phages, this includes transduction which is responsible for transfer of drug resistant features, lysogenic conversion is responsible for acquisition of new characteristics such as the formation of new enzymes, random insertion into bacterial chromosome can induce insertional mutation, epidemiological typing of bacteria ( phage typing ), phages are used extensively in genetic engineering where they serve as cloning vectors.

A key difference between the lytic and lysogenic phage cycles is that in the lytic phage, the viral DNA exists as a separate molecule within the bacterial cell, and replicates separately from the host bacterial DNA . The location of viral DNA in the lysogenic phage cycle is within the host DNA, therefore in both cases the virus / phage replicates using the host DNA machinery, but in the lytic phage cycle, the phage is a free floating separate molecule to the host DNA.
