New research into mitotic chromosomes has found that they are covered in a liquid-like coating that could allow them to bounce off one another, like bumper cars, protecting them from being damaged during cell division.



Summary

Mitotic chromosomes, crucial for accurate cell division, are now understood to have a liquid-like coating. This discovery, based on new research, suggests that this coating acts as a protective barrier. Scientists believe the liquid layer allows chromosomes to repel each other, functioning similarly to bumper cars. This “bouncing” mechanism could prevent chromosomes from tangling or being damaged during the highly dynamic process of mitosis, ultimately ensuring genetic stability in daughter cells. The finding offers new insights into the mechanics of cell division and chromosome behavior.
