[DIYbio] Re: notahelix.net

There are definitely people at Universities teaching that DNA isn't
always in a canonical form. Here are some recent studies that are
getting close and closer to looking at things in their natural state,
we're on our way to approach Heisenberg's uncertainty principle. There
are plenty of people who want to know what is really going on.

How I searched:
(used the terms 'cryo em DNA nucleus in-vivo tomography' and then
chose since 2011, then since 2015, added helical, removed in-vivo,
removed nucleus... etc...)
