Figure 2From: Evolution of alternative and constitutive regions of mammalian 5'UTRsuORF length distributions in alternative and constitutive regions. uORF length distributions between alternative (ALT) and constitutive (CONSTIT) regions of 5'UTR are significantly different in human (A) and mouse (B) (P = 1.1 × 10-26 for human and P = 6.5 × 10-9 for mouse; Student's t-test). uORFs in ALT and CONSTIT regions are labeled as blue and gray bars in histograms.Back to article page
