Group I introns are genetic elements interrupting functional genes. They are removed from precursors at the RNA level and most catalyze their own splicing. The catalytic part of these constitutes one of the major classes of catalytic RNAs, the group I ribozymes. However, group I introns have a lot more to offer than their own elimination by splicing. Intron RNA can circularize in at least three different ways and introns are mobile both at the DNA and RNA level. Some group I introns have a very… Expand
