In contrast to retrotransposons, they never encode reverse transcriptase (RT). Therefore, they are non-autonomous elements with regard to transposition activity (as opposed to transposons). Retroposition accounts for approximately 10,000 gene-duplication events in the human genome, of which approximately 2-10% are likely to be functional. Such genes are called retrogenes and represent a certain type of retroposon. A classical event is the retroposition of a spliced pre-mRNA molecule of the c-src gene into the proviral ancestor of the Rous Sarcoma Virus (RSV). The retroposed c-src pre-mRNA still contained a single intron and within RSV is now referred to as v-src gene. Non-Long terminal repeat (LTR) retrotransposons such as the human L1 elements are sometimes falsely referred to as retroposons. == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Retroposon」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
