Cellular zombies: Mutant cells that can’t copy DNA keep dividing when they shouldn’t

Mutant cells that can't copy DNA keep dividing when they shouldn't

Sequential images of abnormal divisions in a mutant cell leading to abnormal nuclei and chromosome rearrangement. Chromosomes are displayed in pink, cell membranes in green. The cell undergoes two aberrant divisions.
