- A protein complex that holds sister chromatids together during cell division until they separate.
Usage: biology; molecular biology; technical
Examples
- Cohesin proteins are essential for maintaining chromosome structure during mitosis.
- The breakdown of cohesin at the centromere allows sister chromatids to separate during anaphase.
- Mutations affecting cohesin function can lead to chromosomal instability and developmental disorders.
- Researchers study cohesin to understand how cells accurately distribute genetic material to daughter cells.
