When you donate blood or let's say an organ to someone, what happens to your DNA in those cells?

Red blood cells don't have a nucleus and therefore no DNA, so no issue there. Normally for blood donations, the white blood cells (which do have DNA) are removed. In the case of organs, the host cell DNA remains intact, which is why it is necessary to get a match between donor and host, and why immunosuppressive drugs need to be taken regardless.
