The frequency of occurrence and the genetic structure of polylysogens were studied for phages lambda, phi 80 and lambda att80. In the case of lambda, frequency of polylysogenization is high (0.20 to 0.41) with a tandem integration of prophages at the primary att site (att lambda). With phi 80 and la
The family of lambdoid phages displays a varying specificity of integration into the host chromosome. The lambda phage DNA failed to get inserted at the secondary site(s) of the gal operon (frequency less than 2.6 X 10(-8) in the presence of the primary (normal) att site. By contrast, phi 80 and the
