Figure 2.
Profiles of nucleotide base pairing around the start codon (A, C and E) and the stop codon (B, D and F) for 19 317 human mRNAs (A and B), for sequences with randomly chosen synonymous codons (C and D), and sequences with randomly shuffled nucleotides and the same nucleotide composition as native mRNAs (E and F). Blue, guanine; red, cytosine; green, adenosine; orange, uridine.
