Mar-A of Ehrlich-Lettré mouse tumor is actually a "dic".
Mouse ascites tumors are generally characterized by the presence of one or more marker chromosomes. Mar-A, the chromosome hallmark of Ehrlich-Lettré mouse tumors has been characterized differently by different investigators since the time of its first description by Bayreuther in the early 1950s. Our critical analysis of band profiles of mar-A showed that this marker is actually a dicentric (dic) chromosome with asynchrony in centromere separation at the time of mitotic anaphase.
