Table 1 GT and GC donor splice sites and conversion events in AT-rich and GC-rich regions^a

Splice sites/conversion events	%A+T > 50%	%A+T < 50%	P_Fisher/GT^b
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

^aAT content was estimated in ± 100 base pair regions surrounding donor splice sites
^bStatistical significance was estimated by comparing the respective values with the number of GT sites using Fisher's two-tailed test
