ELI5:If a person gets an organ transplant (and assuming their body doesn't reject it) is there a point, after the body's cells have been refreshed with new ones, in which the replacement organ will have no DNA of the person that it originally belonged to?

They refresh their own cells, so it will always have the donor DNA.  Cells don't come from a different place in the body.  The existing cells just split in two, keeping their DNA intact.  The only way to get an organ with your own DNA would be to grow them with stem cells.
