Table 1.

P-values for Student's; t- and F-tests comparing alternative acceptors against constitutive/pseudo acceptors based for the following features: distal splice sites (Dist SS), proximal splice sites (Prox SS), average intronic conservation in 100 nt upstream of the proximal splice site (IC₁₀₀), PPT length, PPT score, distance of PPT to the distal site (PPT∼D) and the proximal site (PPT∼P), ESE/ESS density, pseudo HAG sites and GC content
