Figure 3

A-C and G-T content along the mitochondrial genome of S. velum. A-C (pale blue) and G-T (dark red) contents are computed on a sliding window of size 151 bp. A linear sketch of the complete genome as annotated in Figure 1 is depicted above the plot: blue, PCGs; green, tRNAs; brown, rRNAs; gray, URs >100 bp; genes on the “ + ” strand are above the black line and genes on the “-” strand are below it.
