On the disentangling modes of ortho- and para-braids in mitosing mammalian spermatogonia.
This note complements a previous one (1), regarding in particular, mitotic separation of replica homologs from their templates, in mammalian spermatogonia. Topological differences between Ortho- and Para-braids determine different modes of antipodal segregation of paired homologs prior to onset of meiosis.
