Giving Genetic Disease the Finger

Wired News: Giving Genetic Disease the Finger

I knew the zinc finger concept was incredibly important the first time I read about it, however I thought it was akin to a nanotechnology creation, formed of thousands of zinc atoms. In this article it points out, that zinc fingers are named after "wispy amino acid protuberances that emanate from a single zinc ion". So there is much less zinc involved than I had imagined, and it is all coupled with amino acids.
