Retroposons are repetitive DNA fragments which are inserted into chromosomes after they had been reverse transcribed from any RNA molecule. In contrast to retrotransposons, they never encode Reverse Transcriptase (RT). Therefore, they are non-autonomous elements with regard to transposition activity. (compare Transposons)
