    If red blood cells don't have nuclei, then does this mean we can't find DNA in blood?

    There are many white blood cells in blood that do contain DNA.

    Red blood cells loose their nucleus, because they have to attain a specific spheroid form (to optimize the surface area for gas-exchange), which is impossible with a bulky nucleus.
