[edit] Zinc atom vs. ion
Does a zinc finger bind to a zinc atom or zinc ion? I performed a brief Yahoo search that returned a significant number of hits suggesting it is a zinc ion rather than a zinc atom. Can someone familiar with this topic either confirm or refute this and make appropriate modifications to the article?--GregRM 20:57, 3 March 2006 (UTC)

[edit] Charge of a zinc finger?
I remember learning that a zinc finger is mainly (I think) positive charges, so that is why it binds so tightly to DNA which is mostly (I think) negative charges due to the phosphates. I think a very simple visual explanation like this is good in helping people understand moreso than telling them the exact spots it binds. ~Ryan
