Ellingson, Kenneth L  asked the Naked Scientists:


If the human body's cells replace and we are completely new after several years will a transplanted organ or limb eventually become your DNA and cells?

What do you think?

No, in most cases not.. the cells with which the organ replaces itself are generated by division of cells from within the organ which, having been transplanted in with the organ, will have the same genetic code as the donor rather than the person receiving the donation.
