Fine structure of the phage specific for Bacillus thuringiensis var. galleriae was studied. The head of the phage is of the elongated hexagonal shape, 600 X 360 A. The tail is 400 X 40 A large and has a thickening in the basal part (70 X 120 A). A so-called "collar" structure is found at the site where the head joins the tail. This a disc-shaped plate with(More)
The structural studies of macronuclear chromatin of the ciliate Bursaria truncatella showed that in resting cysts practically all macronuclear chromatin was arranged in compact clumps 100 to 300 nm in size. By means of negative staining the internal structure of chromatin clumps was revealed; the chromatin clumps were shown to consist of subunits(More)
