DNA is just a (very large) molecule, like proteins, RNA, sugars, starch etc. Definitly
not alive (in my not so very humble opinion).

Bacteria are generally considered alive. However viruses are somewere in the
twilight zone between live and dead. They can't replicate with their own
system alone. The discussion will never end, but I favor the 'dead' option.

IMHO: -should be an organised system (of molecules) that can self replicate without
outside interference and able to adopt a bit to the environment.
This is crude and probably not complete, but it's just my humble opinion.
