title: Topologic preconditions for ring chromatids.
abstract: The paper discusses a mechanism apt to convert the topology of a straight chromatid into one that could lead to the formation of a O-ring. It is predicted that such conversions might occur only in exceptional circumstances, due to a combination of poorly correlated events.
