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.

Retrotransposon fragments were amplified using the following primer pairs: FI/B6 (d5'[GCA CTC CAC CAA GAA TAC C]3'/d3' [GGT TTC ACT TTG TCC TTA G]5'); F10/B8 (d5'[TAA GCA AGC ATC TCG GAG]3'/d3' [ATA CCT TTC AGG GGG ATG]5').
Retrotransposon: DNA segment that can duplicate itself and thus multiply in the genome; during this process, the original DNA sequence first copies itself into RNA and then back into DNA, which is then incorporated back into the genome; retrotransposons make up a substantial portion of the genome.
