I do not know as of yet wether it has been tried or not.
I did a google search, and came up with nothing but papers on the possibility of the subject.
If we do build DNA using non carbon-based materials, we will probably still stick to the original carbon based method, as we have alot more
understanding of it at the moment.
Should we find a need to bio-engineer a new life form, it would likely be done using carbon DNA. You would save on having to do excessive research,
plus, we don't know how a non Carbon DNA strand would react to day to day radiation, chemical instabilities, etc. It could end up breaking down and
degrading alot faster than it's carbon counterpart.
