Abstract Polytene and nonpolytene nuclei of Drosophila melanogaster were isolated from larval salivary glands and imaginal discs, respectively. The histones of the two types of nuclei yield identical patterns on gel electrophoresis but differ considerably from those of sea urchins, birds, and mammals in the positions of F1, F2b, and possibly F3. The greatest difference is in the F1 (lysine-rich) histone, which in the case of Drosophila has a much lower electrophoretic mobility. The low mobility… CONTINUE READING
