binding of anti-nucleoside antibodies reveals different classes of dna in the chromosomes of the kangaroo rat (dipodomys ordii). 197770368
mechanisms of chromosome banding. ix. are variations in dna base composition adequate to account for quinacrine, hoechst 33258 and daunomycin banding?prior studies on subfractions of mouse and kangaroo rat dna have suggested that variations in base concentration within a given genome may not be great enough to account for q-banding. to examine this with another species, calf dna was subfractionated by cscl ultracentrifugation into gc-rich satellites and the main band dna was further fractionated into at-rich, intermediate and gc-rich portions. the effect of varying concentrations of these dnas on quinacrine and hoechst 33258 fluorescence was ...197661106
chromosomes of a cell line of dipodomys panamintinus (kangaroo rat). a banding and autoradiographic study.the chromosomes of an established cell line of dipodomys panamintinus have been characterised in terms of their c, g and q banding patterns, and the distributions of silver grains in autoradiographs of chromosomes labelled in early or late s phase. no relationship could be established between c, g or q banding regions of chromosomes and a particular s phase time of replication of the dna in these banded regions. the implication of this result to the concept of heterochromatin is discussed.197549259
