   Comparison of the genomes of humans, yeast, fruit flies, maize and Escherichia coli

(A) is the 50-kb segment of the human β T-cell receptor locus shown in Figure 1.14. This is compared with 50-kb segments from the genomes of (B) Saccharomyces cerevisiae (chromosome III; redrawn from Oliver et al., 1992); (C) Drosophila melanogaster (redrawn from Adams et al., 2000); (D) maize (redrawn from SanMiguel et al., 1996) and (E) E. coli K12 (redrawn from Blattner et al., 1997).
