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?

Hi! I am doing a science fair project on DNA. I found an article stating that 20 babies were born genetically altered (BBC news). I showed my teacher the article and she has doubts whether the article is actually true. So my question is, is there really 20 babies born genetically altered in the U.S?

How is it that DNA can be extracted and read from long past fossils? Doesn't the drying and age affect the DNA? If we can clone a sheep from its DNA, why not a dinosaur?
