Table 1 GT and GC donor splice sites and conversion events in AT-rich and GC-rich regionsa

From: Accumulation of GC donor splice signals in mammals

Splice sites/conversion events %A+T > 50% %A+T < 50% PFisher/GTb
Total number of donor splice sites(%) 51798(100) 71396(100)  
GT 51575(99.57) 71028(99.48)  
GC 88(0.17) 165(0.23) 0.02
GT>GC 113(0.22) 185(0.26) 0.15
GC>GT 22(0.04) 18(0.03) 0.11
  1. aAT content was estimated in ± 100 base pair regions surrounding donor splice sites
  2. bStatistical significance was estimated by comparing the respective values with the number of GT sites using Fisher's two-tailed test
