Chromosome segregation
Chromosome segregation is a step in cell reproduction or division, where chromosomes pair off with their similar homologous chromosome. In mitosis, a complete copy of each one is made. In meiosis, one chromosome from each pair migrates to opposite ends of the cell and the genes are split to make a gamete.
For more information see the Cell Cycle.

Researchers describe new functions of cohesin relevant for human disease
Cohesin is a ring-shaped protein complex involved in the spatial organization of the genome and in mitotic chromosome structure. Vertebrate somatic cells have two versions of cohesin that contain either SA1 or SA2, but their ...

Warwick scientists uncover how 'checkpoint' proteins bind chromosomes
The development of more effective cancer drugs could be a step nearer thanks to the discovery, by scientists at Warwick Medical School, of how an inbuilt 'security check' operates to guarantee cells divide with the correct ...

One for you, one for me: Researchers gain new insight into the chromosome separation process
Each time a cell divides -- and it takes millions of cell divisions to create a fully grown human body from a single fertilized cell -- its chromosomes have to be accurately divvied up between both daughter ...
