[Formation of specifically transducing lambda alpha g-particles. I. Relationship between the quantitative composition of transductants and the type of inductive activity].

To study the formation of specifically transducing particles, different physical and chemical prophage-inducing factors (spontaneous induction, UV and roentgen irradiation, treatment with mitomycin C and nalidixic acid). Each kind of induction used in this study was shown to bring about the formation of transducing particles. The kind of inducing action influenced the qualitative composition of transductants. DNA ruptures caused by inducing factor may be supposed to play the main role in the formation of specifically transducing lambda dg-genomes.
