Comparisons of genome organization. 2A. A comparison between the genomes of N. meningitis Z2491 and N. lactamica 020-06 using ACT . The apparent re-arrangement at the start of the Z2491 genome with respect to N. lactamica 020-06 was because the start of the Z2491 genome was not assigned at the origin of replication. 2B. A dot plot comparing the genome sequence of N. lactamica 020-06 with the seven other complete Neisseria genomes.
