Proteins called cohesins ensure that newly copied chromosomes bind together, separate correctly during cell division, and are repaired efficiently after DNA damage. Scientists have found that cohesins are needed in different concentrations for their different functions. This discovery helps to explain how certain developmental disorders, arise without affecting cell division essential to development.
