DNA in blood cells

    Just a quick stupid question.

    When you donate blood it obviously the blood cells contain your DNA. When that blood is transfused into another person, is the DNA re-writen to contain that persons DNA?

    Thanks.

    I could be wrong but from what I remeber of JC science red blood cells don't contain a nucleus, no nucleus means no DNA. I know red blood cells are quite simple compared to most cells in the body. Presumably white blood cells are transferred also, but they might just die off.

    No, the DNA can't be rewritten like that. Blood transfusions are essentially emergency measures to retain the flow of oxygen and nutrients to the body, usually following blood loss from surgery or an accident.

    Red blood cells only last a few weeks, so the body will gradually make its own during the recuperation phase and the transfused ones will die off.
