Well, i have been given the opportunity to chat with a university professor of the field of Genetics at the University of BC (not sure when, not soon, but my doctor was able to hook me up with the meeting

). So i wanted to somewhat intelligently converse with him the idea of genetic manipulation via Zinc Fingers. In order for me to do this, i was wondering if anyone could further explain how they work? I need to come up with some worth-while questions, as it will likely be about a year before i have a chance to chat with him, and i would rather not waste my one opportunity (and probably 2 year wait including the year i've been scheduled, and the 1 more year to wait) to talk to someone very educated on the subject

!
I have read a bit online about them through the Zinc Finger Consortium website, but i'm having trouble wrapping my head around them completely. Anyone familiar with these able to help me out?
Or perhaps other means of genetic manipulation?
Or anyone know of the article in which scientists have discovered how to convert human cells with the assistance of some moth cells or something, back into human stem cells?
Thanks
Michael
