Mobile group II introns employ a remarkable site-specific DNA integration mechanism, termed retrohoming, in which the excised intron RNA inserts directly into a DNA target site and is then reverse transcribed by the intron-encoded protein (IEP) [1], [2].
Such a remarkable site-selective fragmentation process in biomolecules within a relatively narrow energy range was previously observed in nucleobases.[ 8, 46 The resonance at approximately 5.5 eV: For the resonance at approximately 5.5 eV all dissociation channels are energetically open.
The site was described by MoD archaeologist Richard Osgood as a "truly remarkable site".
Here's how I would stretch my letter-writing muscles to prepare: grab a piece of paper (or, if you want something more exalted than the plain five-and-a-half by eleven, look on the remarkable site Letterheady for ideas).
