1985 J. D. Boeke et al. in Cell 40 496/1 Our data suggest that reverse transcription of Ty, like that of retroviruses, regenerates the 3′U5 from the 5′ end of the message and the 5′U3 from the 3′ end. We therefore propose the term retrotransposon for Ty and related elements.

1996 Economist 20 July 85/1 For more than 500m years, the genes of insects have contained an ancient segment of parasitic DNA called R2. R2 is a retrotransposon.
