Retroposition
<B>1.</B> Simple backward displacement of a structure or organ such as the uterus.<BR><B>2.</B> In genetics, the integration of a sequence derived from RNA into a DNA genome.
Messenger RNA (mRNA) is reverse-transcribed and reintegrated into the genome.
Retroposition is an important mechanism of gene copying.
It produces a large number of functional genes in the genome and accounts for about 10,000 duplications in the human genome
