ISOETES V : GENOMIC RESHUFFLE [A] : DNA SEQUENCES

Common Occurrence of some DNA sequences in humans and plants has been attributed to a matter of chance having no significance. But from evolutionary point of view, their absence in majority and presence in a few species does indicate greater significance than thought of, thus offering evidence in favour of possible genetic mechanisms accelerating genomic reshuffle from time to time in the geological history. The partial genomic assay of Isoetes panti, an aquatic lycopod (pteridophyte), has offered a unique Support to a concept that DNA sequences can be conserved for billions of years and extremely rare genomic reshuffle may revive their functional entity.
