From: Genome-wide analysis of alternative splicing in Volvox carteri

  1. 1 this study, 2[53], 3[26],4[16, 134].
  2. *4.2% show other alternative splicing events.
  3. **0.7% show both alternative 5′ splice site and alternative 3′ splice sites.
  4. *** 32.7 % show other alternative splicing events such as exclusive exon, alternative first exon, alternative last exon and tandem 3′ UTR.
