WebIntrons can be divided into three types based on phases: phase 0, phase 1, and phase 2. A phase 0 intron does not disrupt a codon, a phase 1 intron disrupts a codon between the first and second bases, whereas a phase 2 intron disrupts a codon between the second and third bases. An exon flanked by two introns of the same phase is called a ... WebGroup II introns use intron-encoded reverse transcriptase, maturase and DNA endonuclease activities for site-specific insertion into DNA. Although this type of intron is self splicing in vitro they require a maturase protein for splicing in vivo. It has been shown that a specific region of the aI2 intron is needed for the maturase function.
