[Structure and histone composition of chromatin in Physarum polycephalum].
In Physarum polycephalum several degrees of organisation of deoxyribonucleoprotein fibres were found. The complexes of histones and the DNA duplex seem to "be packed" at first into a 100 A fibre and then into a 200 A fibre of DNP. In Ph. polycephalum the electrophoretic mobilities of histone fractions 4 and 6 are comparable to that of fractions f3/f2b and f2a1 of calf thymus, resp. Histone fractions 3 and 5 move a bit faster than fractions f1 and f2a2, resp. Thus, the myxomycete P. polycephalum is similar to higher eukaryotes as concerns the ultrastructure of chromatin and electrophoretic properties of histones.
