*** Scientists map chromosome 21

(AP) - In an achievement that could point the way to treatments for a
host of illnesses, scientists have mapped chromosome 21, the smallest
human chromosome and the one associated with Down syndrome, epilepsy,
Lou Gehrig's disease and Alzheimer's. It is the second human
chromosome whose DNA has been fully deciphered. Chromosome 22 was
mapped last fall. "Another volume has just been placed on the shelf.
Now we really have to roll up our sleeves and assess what these genes
are doing there, what role they play in causing disease," said
Francis Collins, chairman of the Human Genome Project at the National
Institutes of Health in Bethesda, Md. See
