Fig.1. During cell division, an increase in Mg2+, which is released by the ATP hydrolysis, contributes to chromosome condensation. (credit: National Institute of Genetics & Osaka University)Japanese researchers report a new ion detector, MARIO. Using it, they show that changes in the concentration of free magnesium ions (Mg2+) within the cell is critical for the chromosome folding that must occur for cells to divide. The findings, which can be read in Current Biology, provide a new mechanism for chromosome organization. Cell […]
