title: On ring chromatids.
abstract: The paper studies mammalian chromatids conformed as donut-like rings. Albeit enacting many topologic and dynamic aspects of straight chromatids (e.g. replication, eversion, antipodal segregation at anaphase, etc.), rings differ in certain properties regarding in particular disposal of soliton-like, kinked frustrations of their chirality during recurrent sister chromatid exchanges (SCEs).
