Georg Tremmel and Shiho Fukuhara presented the Biopresence project, proposing to incorporate strands of human DNA into eg. trees. In the case of incorporating a dead relative's DNA into an apple tree, the question is if you would eat the fruit from the grandma tree. Check out: www.biopresence.com. A totally unrelated detail in this connection is Shiho's pseudo dial-up audio watch which will only tell you the time when stimulated whith the right combination of numbers.
