Hover, tap or tab to a feature to see its position, length, strand and GC content. Genes and rRNAs open their own pages.

  • Protein-coding13
  • rRNA2
  • tRNA22
  • D-loop1
  • Outer ring: + strand, arrows run clockwise. Inner ring: − strand.
  • Middle ring: GC% of each gene against the whole genome (46.9%, dashed): out is GC-richer, in is AT-richer (full height = 6 points).
