Whole mount metaphase chromosomes, from cultured L cells, have been centrifuged onto grids and examined by electron microscopy. Compact and dispersed chromosome forms provide extensive ultrastructural information. Condensed chromosome arms appear as packed fibers with centromeric heterochromatin identifiable because it stains more intensely than the rest of the chromosome. Kinetochores are readily visible in these preparations. Under appropriate isolation conditions, it is possible to obtain… CONTINUE READING
