Alternative splicing in human, mouse and rat
and implications for phylogenetic study
from Modrek and Lee (2003)
What is splicing?
Splicing is the process that occurs after transcription of DNA, and by which discontinous coding regions (exons) are assembled into a single mature mRNA.

Type I, Type II self splicing introns, are found in eubacteria, archaebacteria and eukaryotes
Spliceosomal introns are found only in eukaryotes
