The only answer I have come close to is the "hidden break" event of ribosomal subunits reported in mollusks and insects. However, in these studies up to 3~4 bands are reported, in my case I have up to 6 bands (as seen in the attached gel where the integrity of the newly extracted total RNA was evaluated). It is worth mentioning that the molecular marker used (lane 1 of the 1.5% agarose gel) is the Fluorescent Low Range DNA Ladder of 50bp-1kb.
