While I'm happy about cloning, and even see some applications in medicine near term, both introduction AND removal of genes have been already done in animal experiments. One major way to explore how our brains work, right now, is to produce animals lacking the gene for one or another enzyme, or even make animals for which production of that gene can be turned off not everywhere but in some particular area of the brain or at some particular times. Still, cloning is one more advance in our control over life ... a major form of nanotechnology, though many seem not to see that. Best and long long life, Thomas Donaldson Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=8432
