Minimaps For Human Cells
</hdr><body>
<p>Scientists provide the first guides to two chromosomes
</p>
<p> Finding a single gene among the estimated 100,000 genes
scattered along the 23 pairs of chromosomes in human cells is
every bit as daunting as finding the proverbial needle in a
haystack. But now the quest has been made simpler, at least for
two of those chromosomes. As reported in the research journal
Nature, investigators in Paris have published the first map to
describe in the correct order all the most important subsections
of the 21st chromosome -- the one that harbors genes associated
with Down syndrome, Alzheimer's disease and other neurological
disorders. Simultaneously, researchers in Boston published a
similar map, in Science, for the Y chromosome, which is vital
to male development.
</p>
<p> These achievements will help researchers decipher the
genetic blueprint of human beings. They will not, however, by
themselves lead to useful therapies anytime in the near future.
Because of the complicated interplay between heredity and
environment, knowing where a gene is located and what it looks
like is only a first step. Years of research are still required
to determine how and why a particular gene causes a disease and
what treatments will be needed to cure it.
