15 صفحه اولKaryotype Analysis and Chromosome Banding
Nearly all methods of chromosome banding rely on harvesting chromosomes in mitosis. This is usually achieved by treating cells with tubulin inhibitors, such as colchicine or demecolcine (colcemid), that depolymerize the mitotic spindle and so arrest the cell at this stage. Excessively long incubations with Colcemid result in overcondensed chromosomes that band poorly and moreover some cell type...
متن کاملChromosome markers in Mus musculus: strain differences in C-banding.
The mitotic chromosomes of several inbred strains of mice and a series of F(1) hybrids have been analyzed by quinacrine staining and further characterized by the centromeric heterochromatin banding (C-banding). Inbred strains had the same amount of C-banding material on homologous chromosomes but showed variation in the amount on different chromosomes. F(1) hybrids showed characteristics of eac...
