Retrotransposons

retrotransposons

transposable elements (transposons) that involve a retrovirus-like process of reverse transcription. The dNA element is transcribed into rNA, reverse-transcribed into DNA, and then inserted at a new site in the genome.

Re: Experimental evidence for evolution

... architecture is strongly influenced by insertion and deletion events that add and remove DNA over evolutionary time.” The fact is that SINEs being retrotransposons are mutagens, their insertion/deletions are mutational events and by their very nature are therefore Random events. Now please try ...

Re: Experimental evidence for evolution

... SINE’s (Short Interspersed Nuclear Elements) and LINEs (Long Interspersed Nuclear Elements). Both these elements are types of mobile DNA known as Retrotransposons and together comprise about half of the mammalian genome. Without worrying too much about the technical details just focus on the relative ...

Another creationist thread

... There are actually quite a number of ways to add to the length of a genetic code, examples - unequal recombination of homologous chromosomes, retrotransposons(copy and paste). Both of those previous examples can duplicate genes and the copies are seen in gene families that create proteins ...

The Fiber Disease

... HERV-K progeny. 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 ...
