The vegetative phase of both prophages and the super- infecting phage are initiated, and infectious particles of both types will be produced. lysogenic bacterium produces bacteriophage and dies. If, previous to the irradiation, the lysogenic bacterium has been infected with a mutant of the homologous phage toward which the bacterium is immune, the mutant will develop together with the prophage. The problem of the control of viral development is thus posed in the most dramatic way. [72].
