No. DNA, physics, chemistry, etc. are mere accidents.

Or we're told (as I saw on one of the Discovery channels a few weeks ago) that if not mere chance, then the naturalistic origin of life can be explained by "mysterious chemical reactions". Funny though, that scientists don't have an explanation for these mysterious chemical reactions.
So we end up with one of two scientific theories; either the 'theory of chance' or the 'theory of we can't explain it'. I guess Mr. Hawking should have included these in his 'theory of everything'.
