Genome assembly characteristics. A) The graph shows the GC-content and the genome size of completed genome assemblies (thus excluding low-coverage genomes). For better visualisation the genome size is plotted logarithmically. B) The diagram shows the box plot of the genome sizes of some major taxa for which many completed genome assemblies are available. C) Same as B) but the genome sizes are plotted logarithmically to better visualize the sizes of the smaller genomes.
