Scientists at the Carnegie Institution have discovered that cohesons are needed in different concentrations for their different functions. THis new discovery has helped explain how certaian developmental disorders like Cornelia de Lane and Roberts syndrome come about without affecting the cell division essential to development. This research was made possible by a new innovative technique for eukaryotes. This enables scientists to reduce the concentration of a protein in living cells over time. This enables a better understanding of developmental disorders and to the study of proteins with multiple functions.
