Retrotransposons accomplish transposition through a process that involves the reverse transcription of RNA copies of the element into DNA, which is then inserted into a new location in the genome. These elements are also referred to as retroelements or retroviruses, and are believed to have played a significant role in the evolution of eukaryotic genomes. Cut and paste transposons and replicative transposons both achieve transposition by excision from one site and insertion into another, but do so through different mechanisms. Cut and paste transposons are excised directly from the genome and reinserted elsewhere, while replicative transposons create a new copy of the element that is inserted into a new location.
