Neither is a collection of biopsies without corresponding specimens. Don't
laugh, such "collections" do exist in some labs... unfortunately for their
owners, there are no more "biopsies" than there are "sequences" running
freely out there, waiting for modern biologists to study them. DNA simply
cannot be the first way to describe the biological diversity of organisms.
