retrotransposon

[¦re·trō·tranz′pō‚zän]
(cell and molecular biology)
A small, mobile deoxyribonucleic acid (DNA) sequence that can retrotranspose, that is, move from one genomic location to another by producing ribonucleic acid (RNA) that is transcribed by reverse transcriptase back into DNA which is then inserted at a new site.
