When scientists clone an animal, how do they reprogram the DNA to make an embryo instead of whatever the cell used to be? I know it's called "somatic cell nuclear transfer," but how does moving the nucleus into an egg reset it's DNA?

I don't think we will ever need to clone humans because we will have "body 2.0" and organs such as the heart will not be needed, because the blood will use nanotechnology to pump itself through the body. Do you think that body 2.0 will prevail over cloning? Why or why not?

I am a 53 year old woman who underwent removal of her uterus after two operations for uterine fibroids. I insisted on keeping my ovaries, however, to prevent premature menopause. By now I assume that my eggs are greatly deteriorated and heroic attempts to fertilize them would likely result in an unhealthy fetus. However, is there a way to retrieve healthy DNA from other cells in my body, implant my DNA in the nucleus of a donor egg whose own DNA has been removed, fertilize my egg(s)with my husband's sperm, implant the egg(s)in a donor womb, and obtain a healthy fetus that is genetically like my husband and me?
