The buoyant density of the granulosis virus DNA was 1.703 g/cm(3) and that of its insect host DNA was 1.697 g/cm(3). The molecular weight estimated from length measurements in electron micrographs was 76 x 10(6). The molecular weight of the viral DNA was calculated to be 81 x 10(6) by sedimentation in neutral sucrose and 78 x 10(6) by sedimentation in alkaline sucrose. The superhelical molecules were converted to relaxed circles by treatment with pancreatic DNase. The social networks in these groups seem to turbocharge. ![]() Electron microscopic visualization of the DNA that banded at the higher density in the latter gradients revealed supercoiled structures whereas that of DNA that banded at the lower density demonstrated relaxed circular molecules. Virus outbreaks have been spreading in a particular type of community: tight-knit and traditional. ![]() These molecular forms were indicated by the production of two radioactive bands during sedimentation of (3)H-labeled granulosis virus DNA in alkaline sucrose gradients or in equilibrium density gradients of neutral cesium chloride/propidium iodide. The remaining 75% consisted of relaxed circular molecules. Twenty-five percent of the DNA extracted from purified virus was isolated as supercoiled circular molecules. The DNA of the granulosis virus of the Indian meal moth, Plodia interpunctella, was characterized by physical chemical and electron microscopic techniques.
