Abstract:
:With an improved N-banding technique, the location of nucleolar organizing region was determined in 27 kinds of material including mammals, a marsupial, birds, amphibians, fishes, an insect and plants. In most cases the N-bands were clearly located on certain specific regions of chromosomes, such as the secondary constriction, satellite, centromere, telomere and heterochromatic segment, while in some species they were detected as very minute bodies distributed over many chromosomes. From the available cytological and biochemical data it was suggested that the N-bands represent certain structural non-histone proteins specifically linked to nucleolar organizers in various eukaryotic chromosomes.

CHROMOSOMA文献大全abstract::When A-banded human chromosomes mounted in water are transferred to an organic mounting medium, the chromosomes show uniform bright quinacrine fluorescence. This change is reversible. It is inferred that quinacrine is bound uniformly along the chromosomes, and that Q-banding is a consequence of a non-uniform distribut...
