mitotic spindle elongation without chromosome separation mitotic spindle elongation without chromosome separation with centromeric DNA associated with spindle midori spindle elongation without chromosome separation with centromeric DNA associated with spindle during mitotic cell cycle mitotic spindle elongation without chromosome separation with centromeric DNA associated with spindle during vegetative growth FYPO:0004211 2014-12-19T12:51:21Z A cellular process phenotype in which mitotic spindle elongation begins, but mitotic sister chromatid segregation stops before completing separation of chromosomes, DNA remains in a single mass at or near the midpoint of the mitotic spindle, and centromeric DNA is closely associated with the mitotic spindle. incomplete mitotic sister chromatid segregation, with unseparated DNA and centromeric DNA associated with spindle
