title: On monosegmental sister chromatid exchanges (SCE).
abstract: Considerations are given to special features of the nuclear envelope that might occasion segmental exchange between sister chromatids. The underlying dynamics may lead to illegal apposition of originally distant sequences and/or to modulations in the topologic orientation of genes on chromatid segments involved in such exchanges.
