# Mutation rate varies according to environmental conditions.
I also believe that in a living cell some bits of DNA have evolved to be more (or less) prone to mutation, according to whether variation in thoses areas helps survival or not.

I think it has been done artificially in an experimental way, but the data rate (encoding / decoding) is terrible because it's pretty much manual.

# it would be so beautiful if it could be made to work
a sort of back to roots thing

# They are trying :)
I think the main interesting thing is that it would (apparently) give a higher density of data storage than current solid state technologies. That might not be true by the time they make it practical, though....

# from wiki:
"1.8E22 bits (2.25 zettaoctets) – amount of information which can be stored in 1 gram of DNA", sounds hard to beat to me

# '1.8E22'?
whoever wrote that article needs to learn to right in standard form:
1.8x1022

# it was written like that
but when i pasted it, it lost the formatting, and i couldnt be bothered to add it back in, since most people know what it means anyway

# ah reet
fair enough, thought some cunt at wikipaedia had well, been a cunt at wikipaedia.

# It's a lot...
But bases are reasonably sized molecules, not to mention the sugar phosphate 'scaffolding'; it's not totally unreasonable to imagine you could build something which handled the same amount of data with fewer atoms; or trim some of the extra stuff away, start substituting other atoms, or use other base modifications (e.g. methylation, glycosylation, I think) to increase data density.

# true
i guess one of the denseist you could get is a lattic of e.g a metal with two atoms, with the atom at the lattice point dictating the 1 or zero.

use Li/Na, one mole~10gms, which would give Nabits (Na= avagadros number)=~10E22B/gm, which is about the same, which makes me suspect that wiki may be lieing

# That's bits stored per gram, which might be true.
Carbon and hydrogen atoms are lighter than sodium and lithium respectively....

# yes but dna has got lots of them per bit of data
plus the suger phosphate back-bone

# True.
