What is the genetic mutation "Originally, we all had brown eyes," said Professor Hans Eiberg from the Department of Cellular and Molecular Medicine. "But a genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a "switch," which literally "turned off" the ability to produce brown eyes." The OCA2 gene codes for the so-called P protein, which is involved in the production of melanin, the pigment that gives colour to our hair, eyes and skin. The "switch," which is located in the gene adjacent to OCA2 does not, however, turn off the gene entirely, but rather limits its action to reducing the production of melanin in the iris -- effectively "diluting" brown eyes to blue. The switch's effect on OCA2 is very specific therefore. If the OCA2 gene had been completely destroyed or turned off, human beings would be without melanin in their hair, eyes or skin colour -- a condition known as albinism...
anyway, I'm back on my blog, til I get outta Facebook jail. when you do this, Sheri, you are missed. not really, nobody cares about anybody.
ReplyDeletestill missing Deoge.
ReplyDeletea lot shit, Sheri, huh, on sz.com. yeah. you've always thought needed it, support. yeah. do you? really don't know. nobody close to me asks anything about my sz.
ReplyDeleteis it like nothing to my family? did I put up a huge facade? do they think I'm just getting a free check?
ReplyDeleteFletch may want to, but he never does.
ReplyDeletewould make a good PBS documentary, Sheri. I'm sure it already is, or will be.
