Barcodes of some organisms. Barcodes of (a) Human chromosome 1 (226.21 Mbps); major components of human chromosome in a composite form: (b) repetitive sequence, (c) promoter sequence, (d) coding regions and (e) introns; and (f) coding and (g) non-coding regions of E. coli K-12. Only a 639-Kbp region of each sequence in (b) – (g) is displayed so each pixel represents the same sequence length. 639 Kbps is used since this is the length of the shortest region among them all, i.e. the total non-coding region of E. coli K-12. Mitochondrial genome barcodes of (h) C. elegans (13794 bps) and (i) Drosophila melanogaster (19517 bps). Plastid genome barcodes of (j) aquatic plant Ceratophyllum demersum (156252 bps) and (k) land plant Populus trichocarpa (157033 bps).
