  abstract  = {Some chromosomes in transformed rat cells and somatic cell hybrids fail to display the presence of kinetochore proteins as detected by antikinetochore antibodies. Suchchromosomes (K- Chromosomes) may constitute a novel mechanism for the genesis of aneuploidy. Wehave analyzed primary~ immortalized and malignant marnmalian cells for the presence of kinetochore proteins and micronuclei. Our resuJts suggest a correlation of the K- chromosome and micronucleus frequency with the variability in chromosome number. Upon in situ hybridization with the minor satellite and alpha satellite sequences some Kchromosomes showed a signal. This indicates that the observed lack of kinetocbores is not necessarily due to a lack of centromeric DNA. We conclude that dislocated K- chromosomes may become incorporated into micronuclei which are prone to loss. Such events would be associated with the generation of aneuploidy.},
