Mar 18, 2022 at 4:59 | comment | added | Maximilian Press | @uhoh We're getting a little off-topic, but sure. Mutation resistance is a feature of some organisms, look at D. radiodurans. There are many error correction processes that are normal in cell biology, they just aren't perfect. Conserved sequences are usually conserved for a functional reason as you say, we usually can understand why. In terms of very large genomes like redwood, they are mostly the outcome of polyploidy or arms races between selfish elements. shrug | |

Mar 17, 2022 at 23:18 | comment | added | uhoh | @MaximilianPress yes I understand. We do have the concept of conserved sequences but resistance to mutation may require they are either necessary for life or quite durable due to some error correction or redundancy which may not be a fully explored bioinformatics concept yet. Wild speculation to illustrate a point; perhaps the huge genome of some plants contains so many copies of the same message encoded in so many different ways that it can be reconstructed even after substantial mutations? | |
Mar 17, 2022 at 23:09 | comment | added | Maximilian Press | @uhoh All of the research referenced by OP seems to be predicated on storage of DNA outside of organisms. I don't think long-term information storage as exogenous DNA inside of organisms makes sense; we have a hard enough time with short-term DNA storage as e.g. plasmids or BACs. Willing to be proved wrong about this, just seems implausible. | |
Mar 17, 2022 at 22:34 | comment | added | bob1 | @tsttst that would be worth expanding into an at least partial answer. | |
Mar 17, 2022 at 22:29 | comment | added | uhoh | @MaximilianPress "...is usually not incorporated into organisms..." *by humans. This question is about "Expanding the SETI initiative..." by searching for sequences put into earthbound genomes long ago by extraterrestrials if I understand it correctly. | |
Mar 17, 2022 at 22:27 | comment | added | uhoh | @bob1 That certainly could be, thanks for the reminder! This question is too old to migrate so one would have to post a new question. I don't think I'll do that but anyone else is welcome to. | |
Mar 17, 2022 at 22:03 | comment | added | bob1 | @uhoh Interesting - would it be more likely to get an answer at the Bioniformatics SE, rather than here? | |
Mar 17, 2022 at 15:07 | comment | added | tsttst | There are now (2022) efforts in this direction, e.g.: cnbc.com/2020/02/28/… ; These approaches however would be more inclusive as searching for molecules that resemble DNA (also in terms of storage) but might are formed through slightly different chemistry. Further the first step seems to be finding molecules (rather than already investigating their sequences). | |
Mar 16, 2022 at 17:38 | comment | added | Maximilian Press | DNA as a storage medium is usually not incorporated into organisms, as I understand it. Looking at e.g. this article, they do not appear to be talking about DNA stored in an organism, but rather synthesizing naked DNA that would then probably be stored as a desalted solid under non-reactive ambient conditions (the most stable case). Organisms have an annoying habit to mutate, and there would be no selective pressure to maintain such a message (without a lot of extra complicating bioengineering). | |

Mar 28, 2013 at 18:46 | comment | added | Everyone | +1: I had the idea about DNA as database too, but it didn't occur to me to marry that thought with distributed computing initiatives! Well done! | |

Mar 28, 2013 at 1:53 | comment | added | Alex Stone | The question is about bioinformatics - is anyone looking for "long storage" data within DNA sequences. | |

Mar 27, 2013 at 18:17 | comment | added | terdon | Unfortunately most of the highly conserved non coding material that you mention comes from viruses which are not really prime candidates for intelligence. | |
Mar 27, 2013 at 17:56 | comment | added | Drosophila | You suggest an interesting idea, but what's the question? | |
