The distinct genome architectures of prokaryotes, unicellular eukaryotes and multicellular eukaryotes.
Genes are shown by rectangles with the arrowhead indicating the direction of transcription. Exons are shown by rectangles without arrowheads. Intergenic regions are shown by straight lines, and introns are shown by squiggly lines. The schematic is not to scale.

Genome size versus the number of protein-coding genes for selected organisms from different divisions of life.
The plot is on a semi-logarithmic scale. Black squares, large DNA viruses; green diamonds, bacteria; red diamonds, archaea; blue circles, unicellular eukaryotes (including fungi); orange circles, multicellular eukaryotes (plants and animals). The data were from the NCBI Genome Project database (NCBI Genomes 2008).

Comparison of gene orders in prokaryotic genomes.
In the genomic dot-plots, each point corresponds to a pair of orthologous genes identified as bidirectional best hits in BLASTP comparisons of the complete sets of protein sequences encoded in the corresponding genomes (Tatusov et al., 1997).
(a) nearly complete colinearity with a few breakpoints: Borrelia afzelii strain PKo vs B. burgdorferi starin B31.
(b) moderate genome rearrangement in bacteria, X-shaped pattern indicative of inversion around the origin of replication: Xanthomonas axonopodis pv. citri strain 306 vs X. campestris pv. campestris strain 8004.
(c) moderate genome rearrangement in bacteria, X-shaped pattern indicative of inversion around the origin of replication: Pyrococcus horikoshii OT3 vs P. abyssi GE5
(d) Extensive genome rearrangement in bacteria: Streptococcus gordonii str. Challis substrain CH1vs S. pneumoniae D39.
