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…
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
