<p> That bacteriophage PBS 1 contains DNA of a considerable size is suggested by the size of its head, and also by the fairly high frequencies with which it performs joint transduction of genetic markers. Density differences between the active, plaque-forming particles and the transducing particles of PBS 1 facilitated a separation of the two which served as a preliminary to investigating the DNA content of each. The molecular weight of DNA obtained from active particles is estimated to be 1.9 x 10^8. Tentative evidence is offered for the presence of a large fragment of host DNA within the head of transducing PBS 1.</p> / Thesis / Master of Science (MSc)
