The group I and group II introns have the remarkable ability to excise themselves from an RNA. This is called auto-splicing, or self-splicing. 

Group I introns are more common than group II introns.

Two transesterification reactions takes place for 2 exon -1 intron configuration. First transesterification is catalysed variably either by external G or branch point while second transesterification is always caused by exon 1 -3’OH.

There are three type of Splicing signals 

Major U2-type or GU-AG introns

Minor U12-type or AU-AC introns
