Abstract
Retrotransposons are a class of mobile DNA elements that utilize an RNA intermediate to move within the genome. These elements are categorized into LTR retrotransposons (derived from ancestral exogenous infections by retroviruses) and non-LTR retrotransposons (mainly LINEs and SINEs). Moreover, occasionally, the machinery of LINEs can capture other mature mRNAs (in trans) and re-insert th…
