Group I intron is a catalytic RNA molecule, or ribozyme, which catalyzes its own selfish splicing, sometimes with the assistance of protein-based splicing cofactors or stabilizers. Subsets of these introns include embedded open reading frames, sometimes encoding homing endonucleases that contribute to propogating mobility of the intron.
