WebGiven the challenges of DNA strand separation and its vital importance, it is not surprising that cells have developed many strategies for promoting unlinking. We summarize seven different factors that contribute to strand separation and chromosome segregation. These are: (1) supercoiling promotes unlinking by condensation of DNA; (2) unlinking ...
