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...
shortly after, we went back to visit, Handicare. I knew they missed Beth. and her, her best friend, Shariff. good decision, considering your son, his fits moments, wanting only to see your mom and fletch? good decision.
ReplyDeletethat one day, in the apartments here, you knew you had lost your son. Called your mom to come get him. yeah. they probably blamed me for all that too, all of mass media.
ReplyDeletethat amounted to about 10 percent of time, Sheri, you're exaggeracting!
ReplyDeletewell, it happened a lot in the car, going to library, wanted to go to grandma's. screaming. I could barely handle it.
