TABLE 2.
Number of genes with unique alternative poly(A) sites
| No. of poly(A) site(s) per mRNA | No. of genesa | % |
|---|---|---|
| 1 | 2716 | 67 |
| 2 | 913 | 23 |
| 3 | 296 | 7 |
| 4 or more | 132 | 3 |
| Sum | 4057 | 100 |
These genes are selected from those that have at least one authenticated poly(A) site from the 17K data set. Note that the genes considered here are only a part of the total gene number from the gene catalog of ∼15,000.
