Cells cope with altered chromosome numbers by enhancing protein breakdown
When chromosomes are lost or gained, massive changes in gene expression disrupt the delicate balance of proteins in a cell. Yeasts with incorrect chromosome numbers counteract this by degrading excess proteins.

Several transient binding events create a strong, adaptable interface between organelles
Rapid communication between intracellular structures such as the endoplasmic reticulum and the mitochondria is crucial for the coordinated functioning of cells. Such interactions occur mainly at sites where the compartments are in direct contact, and are mediated by specific tethering machinery. High-speed single-molecule tracking reveals a well-regulated interface at which many rapid binding and unbinding events provide highly adaptable interactions.
