Whoa, there are literally thousands of people said to have performed miracles, and some, witnessed in our own time. Not one person has made claim to a divine origin or DNA.
Whoa onto thine own self. Mere human beings do not perform miracles. They are, if in a state of grace, the agents through which god performs miracles, or they intercede between other humans and god to petition god to grant miraculous answers to prayer. When a monk is seen to miraculously float through the air, it is not of his own volition or powers that he does so; it is through an act of god. Jesus, being god incarnate, is the direct agent of the miracles he performs. I am not insisting that jesus (the one that originated the religion) or any of his bodily fluids had divine DNA. I am merely suggesting it as a rational possibility that would allow one to determine if bodily remains are truly of divine origin. I say 'rational possibility' because all men (and women and children) since Adam have been cursed with sin and the punishment of disease, as exemplified by the bacterial and viral adduced pseudo-genes in the human genome. But, whether 100% or 93.675% human, jesus was delivered onto the earth free of sin and one would suspect, free of those pseudo-genes.
