A single-celled organism called Chromosphaera perkinsii appears to possess a embryonic process similar to animal mitosis, even though the organism separated from animal’s evolutionary line a ...

Chromosome motion during mitosis can be explained by combining the facts available about the equilibrium between the mitotic spindle and its subunits with the postulate that the recently described ...

Animal reproduction requires that oocytes undergo a specialized cell cycle called meiosis, in which two functionally distinct divisions occur in rapid succession to reduce genome ploidy (Kishimoto, ...

Ploidy-increasing cell cycles drive tissue growth in many developing organs ... Using an acute injury model, we identify mitosis as the response in larval pyloric cells, whereas endocycles occur in ...
