I have seen it claimed there are thousands of Eucharistic miracles, where what appears to us to be wafer and wine by their accidents, but in actuality are Jesus in substance, have their accidents also turned into what appears to us to be physical flesh and blood.
I have also read at least once such tissue was scientifically examined. Since all the miraculously transformed objects are the same person, Jesus, they should all have the same DNA. Has DNA ever been extracted from the tissue? If so, has there been an attempt to scientifically examine multiple such tissue from independent miracles, and verify whether the DNA is all the same?
