      considering that DNA is madeup of base pares all that is really needed to determine its makeup is a simple peice of single helixed RNA (with the help of reverse transcriptase) so why have all “liveing” things based them selfs upon DNA and only use RNA as messenger protines

      some how I doubt there is a single “real” answer to this question but I thought I’d put it out there

      PS I’m more interested in the devlopment of this in humans

      Cells have based their evolution on the double-helix double-catenary molecule of DNA becuase it is much more stable than RNA.
      I don’t think reverstranscriptase is found in other places than retroviruses…

      yes, this I already know and yeah it is only in retro-viruses.

      I just thought it was interesting that it only evolved in retro-viruses. Another thing I thought was interesting was what enviromental conditions could have prompted that evolution?

      Well, it is a nice way of turning RNA into DNA… Because the cell has DNA…
      No organism ever needed this system because DNA is not “created” in cells, it replicates semiconservatively. That is why you can only find in retroviruses

      That’s why retroviruses are interesting to ‘investigate’ on i believe 😯
