() Cluster analysis of PAS hexamers and poly(A) types. The grayscale heat map represents the percentages of usage of PAS hexamers in different poly(A) types, with the sum of all values for each poly(A) type set to 100%. The shade of a cell indicates its value, with darker ones corresponding to higher values. Two-way hierarchical clustering was conducted using Euclidean distance as the metric. () Percentage of the number of supporting cDNA/EST sequences for different types of poly(A) sites. The total number of supporting cDNA/EST sequences for a gene is set to 100%. () Distribution of the number of cleavage sites per poly(A) site for different types of poly(A) site. Different shades are used to represent the number of cleavage sites per poly(A) site.
