Just a few more details -- the human genome is not really completely
decoded. But probably all the parts that really count have been.
There are technical reasons why two particular regions of each
chromosome can't be decoded but these regions almost certainly
don't code for any genes. And what we have now is still called a
In general, two people differ in about 0.1% of their DNA. That is one
out of 1000 base pairs may differ. So perhaps 3 million out of the 3
billion bases differ between individuals. The work is just barely getting
started on cataloging these differences. Trying to understand just what
the differences actually mean is still far away (except in a few exceptional
