you'd have 146 neutrons in that nucleus. so we have all the atoms, all the atoms which differ from one another principally by the number of protons in the nucleus, because anything that has three protons will hold three electrons, no matter how many extra neutrons you put in. and chemically, there's no difference between one isotope and another. chemically, it has to do with mostly this atom here, how that is compared to this, the configuration. and so if you have 92 naturally occurring atoms, then you have 92 different patterns of levels of electrons. and you have then 92 different atoms with different properties. that's when we have the elements, 92 through uranium. got such thing? now, atoms: atoms are mostly empty... because this is grossly exaggerated. i've drawn these very, very big compared to what this is. a better thing would be like if i draw the nucleus here, then out across the street the electron would be. the atom is as empty of matter as the solar system is as empty of masses. you know, you got the sun and the

so there's a technique that takes out the nucleus that has all the good chromosomes from a mother andin monkeys and mice and had been triered in the 1990s in an experiment in new jersey where they were doing it on children without permission. and the fda's debating it yesterday and today about its safety. >> do you have any problems with this? >> i've got a lot of problems with it in that we don't know really, first of all, the safety in the child. you're committing a child to be part of an experiment for the rest of his life honestly without their permission. and then whose job is it in our country to actually say this is the moral and ethic backbone that we have to live by? the fda addresses its safety but who starts the conversation and actually starts to make a decision about some of these bigger questions. >> yeah. and what are the medical and ethical issues because some say now we're going down a slippery slope, designer babies. >> that's a ways away. it's not affecting the chrome zone but it certainly could head there. we don't know its safety. you're right. when we get to that

if there's problems with the mitochondrial dna, they left out the eck's nucleus.s for height, weight, color in tact. and move it to a healthy donor egg. with healthy mitochondrial egg. now the enhanced egg can be fertilized in a lab by the father's sperm and the embryo would be implanted back in the mother like regular ivf. researchers in oregon tried this in monkeys. it worked. they also tried it in human eggs but never implanted them. the fda saying the controversial procedure wasn't yet approved for human trials. this morning, questions remain. is it safe and is it a good idea? >> so, rich, talk about the dna that is the centerpiece. >> yeah. so this is called mitochondrial dna. they have mitochondria that provide them with energy in their eggs. if its infective, they may have a baby with a birth defect. >> promising technique? >> you know, it is. the idea you can make a fix before a baby is born so a couple can have a healthy baby is terrific. it's been done in monkeys. i think it could be done here. >> of course, there are people that are concerned about the

if there is a problem with what's called the mitochondrial dna, doctors take out the egg's n nucleus and moves it to a donor egg. this is an egg that is a much healthier mitochondrial dna. the enhanced egg free of problematic dna can be fertilized by the father's sperm. are you with me? the embryo would be implanted back into the mother. let's talk about why maybe people should be frightened and maybe people should be excited. president of the council for responsibility genetics and director of the division of reproductive infertility. welcome to both of you. >> thank you. >> jeremy, first you. we know that researchers in oregon tried this with monkeys. that was a success. you say this is moving too fast. i want to you tell me why. >> the research to date has shown that there is a lot more work that needs to be done to ensure that the technique is safe. even the fda hearing has been going on for the last two days. they found almost unanimously that a lot more animal testing and other modelling and work is required. basic research is required to ensure that this technique is safe befo
