Cell biologists decipher signal that ensures no chromosome is left behind — ScienceDaily

Starting as a single cell, organisms undergo millions of generations of divisions to ultimately generate the bones, heart, brain and other components that make up a living being. The mainspring within this intricate process is the transfer of DNA through each subsequent cell split within discrete packets called chromosomes. It’s critical that all chromosomes are […]

Cell biologists decipher signal that ensures no chromosome is left behind

A human cell is featured during mitosis with its chromosomes (gray areas) aligned. The region known as the kinetochore (colored with yellow, red and cyan markers) is the origin of the checkpoint signal that acts as a safety check against premature cell division and is the focus of UC San Diego researchers’ study.
