Sines

... We also show that this element amplifies via an extracellular pathway involving reinfection, at variance with the non-LTR-retrotransposons (LINEs SINEs) or LTR-retrotransposons, thus recapitulating ex vivo the molecular events responsible for its dissemination in the host genomes. We also show ...

... transpose by means of an RNA intermediate. They include long terminal repeat retrotransposons and long and short interspersed elements (LINES and SINES, respectively). Long terminal repeat retrotransposons are closely related to other retroelements of major interest, such as retroviruses (5). ...

What is the role of ALu in transposons? I know that LINEs have the mechanisms needed for jumping around chromosomes and that SINEs use LINEs, but I don't know the role of ALu.

... I don't clearly remember what this time, but I will try to find it. an example of a function of intron sequences is..the retrotrasposons(LINES,SINES..)..am I completely wrong?they should have among others the capability to autocleave themselves and transfer and integrate in another site.
