Answer 1

Basically no. DNA is inside your cells, specifically the white blood cells in blood. Your body doesn’t open up cells to check the insides, it checks the outside surface of cells. The A, B, O, positive, negative, etc describes protiens on the surface of the cells. If the code on outside the donated blood is close enough to yours, your body leaves it alone.
