The fibers and range of reduction graphs in ciliates

Original article


The biological process of gene assembly transforms a nucleus (the MIC) into a functionally and physically different nucleus (the MAC). For each gene in the MIC (the input), recombination operations transform the gene to its MAC form (the output). Here we characterize which inputs obtain the same output, and moreover characterize the possible forms of the outputs. We do this in the abstract and more general setting of so-called legal strings.
