Group I introns,such as those found in Tetrahymena,are unique in that they are excised from mRNA by a protein-driven catalytic reaction.

Question

Quizplus · Accepted Answer

Group I introns are excised from mRNA through a self-splicing mechanism, not a protein-driven catalytic reaction. This process is RNA-catalyzed and involves the intron folding into a complex three-dimensional structure that facilitates its own excision.
