Transposons move by means of a DNA intermediate while retrotransposons move by means of an RNA intermediate. Retrotransposons reverse transcribe their RNA into DNA, which is then inserted into the genome at a new location, while transposons directly excise and reinsert themselves elsewhere in the genome.
