Abstract

Introns belonging to the group I or group II self-splicing types are mobile elements that can move into unoccupied sites in homologous genes (homing), or into new genomic sites (transposition). This mobility is mediated by intron-encoded proteins: site-specific endonucleases in the case of group I introns and chimaeric proteins containing reverse transcriptase activity for group II introns.

Keywords:

  • double-strand break repair;
  • reverse splicing;
