Figure 2
Nucleotide composition of four complete vermetid genomes. For each species, the %AT content, AT-skew, and GC-skew are shown for the "+" strand of the complete genome and its functional components, including: protein-encoding genes (complete protein, 3rd codon positions only, and 3rd positions of 4-fold degenerate (4FD) codons only), rRNA genes, unassigned regions (UR), and tRNA genes (including "+" and "-" strand encoded genes). Error bars refer to standard errors based on a sample size from each genome of: 13 protein encoding genes, 14 -15 "+" strand tRNA genes, and 7-8 "-" strand tRNA genes.
