Query: The Fibers and Range of Reduction Graphs in Ciliates   The biological process of gene assembly has been modeled based on three types
of string rewriting rules, called string pointer rules, defined on so-called
legal strings. It has been shown that reduction graphs, graphs that are based
on the notion of breakpoint graph in the theory of sorting by reversal, for
legal strings provide valuable insights into the gene assembly process. We
characterize which legal strings obtain the same reduction graph (up to
isomorphism), and moreover we characterize which graphs are (isomorphic to)
reduction graphs.
