New Understanding of Human DNA
Posted on November 23, 2006 Comments (4)
Very interesting Genetic breakthrough that reveals the differences between humans (bozo website broke the link – poor usability):
It now appears much of the variation is explained instead by people having multiple copies of some key genes that make up the human genome.
Until now it was assumed that the human genome, or “book of life”, is largely the same for everyone, save for a few spelling differences in some of the words. Instead, the findings suggest that the book contains entire sentences, paragraphs or even whole pages that are repeated any number of times.
Fascinating information that I must admit I am still trying to grok.
The studies suggest variations in the number of copies of genes is normal and healthy. But the scientists also believe many diseases may be triggered by an abnormal loss or gain in the copies of some key genes.
It will be very interesting to see how this understanding develops.
