This would be possible but not a good data storage strategy - high mutation rates would lead to very rapid data degradation. A workaround would be to design a highly redundant encoding so the probability of sequence modifications altering the encoded information was low.
- 3pt14159 13y agoNo it doesn't work like that, mutation isn't uniformly high, some sectors are very stable.
- kyberias 13y agoWait, yes it does! Mutation rates may be small over generations due to SELECTION. We're talking about nonsense DNA that does not have any purifying selection pressure, ie. it does not encode any useful or critical protein for the organism.
- 3pt14159 13y agoBut some segments of DNA are effectively unchanging and you can place the message in those segments "junk" sub-segments.
- arca_vorago 13y agoAnd that, ladies and gentlemen, is how the zombie apocalypse started... Anyway, those areas you guys are calling non-coding and "junk" do a lot more than we understand, and I would venture modifying them willy nilly could have some pretty nasty outcomes.
- 3pt14159 13y agoActually, we're beginning to understand them more and more. Remember, if it was as easy as a mutation here or there then the zombie apocalypse would have already started. I'm much more afraid of grey goo (look it up) than punching out some TAGACAs.
- arca_vorago 13y agoOn the ZA, who says mutation is the mechanism, maybe someone wants the ZA to start.... On non-coding regions, we are indeed learning more and more, but these developments are relatively recent and there is much more to be discovered. As for the grey goo... well, that would be quite the singularity, wouldn't it?
- Blahah 13y agoIt does work like that: in bacteria (as in the OP), there are no highly stable intergenic regions, and in viruses (as in grandparent's suggestion) where there are rarely significant intergenic regions at all, the mutation rates are the highest recorded.
