From: Sorting genomes with rearrangements and segmental duplications through trajectory graphs
A trajectory graph. The initial genome consists of one linear chromosome of 5 genes, (1, 2, 3, 4, 5). The duplication operation inserts a copy of (2, 3, 4) to the right end, which transforms the genome into (1, 2, 3, 4, 5, 2', 3', 4'). Then two DCJ operations, one inverting the segment of (4, 5, 2') and the other inverting the segment of (1, 2), generate the final genome as (-2, -1, 3, -2', -5, -4, 3', 4'). Adjacency nodes (1, 2) and (4, 5) form two trivial connected components, while the rest of the graph forms a nontrivial connected component. Figure legend text.
