Really! Have you seen this DNA with your own eyes? Did it look like this ?
Actually yes, DNA can be seen, and is a physical entity. As far as seeing it with my OWN eyes, I don't own the equipment (I wish I did) but others can produce differing images for me if I requested the results of a DNA test from this hypothetical piece of bone. DNA is entirely proveable based upon images, facts and tests (which should be repeated so results can be replicated). Replication of results is important in any study, test, theory or hypothesis.
