Algorithms for Finding Gene Clusters
... For prokaryotes, it is also known that, in the vast majority of cases, functionally associated genes of a gene cluster lie on the same DNA strand [20,12]. We take this into account by constructing signed permutations where the sign of a gene indicates the strand it lies on. We then determine all com ...
