Query: Recent advances on the non-coherent band surgery model for site-specific
  recombination   Site-specific recombination is an enzymatic process where two sites of
precise sequence and orientation along a circle come together, are cleaved, and
the ends are recombined. Site-specific recombination on a knotted substrate
produces another knot or a two-component link depending on the relative
orientation of the sites prior to recombination. Mathematically, site-specific
recombination is modeled as coherent (knot to link) or non-coherent (knot to
knot) banding. We here survey recent developments in the study of non-coherent
bandings on knots and discuss biological implications.
