Public
Access To The Human Genome The
DNA sequence of the Human Genome is now freely accessible to all, for public or
private use, from the National Center for Biotechnology Information (NCBI). The
Center is a part of the National Library of Medicine at the National Institutes
of Health. The
web address for the Human Genome home page is: http://www.ncbi.nlm.nih.gov/genome/guide/human.
The
completion of a "working draft" of the human genome -- an important
milestone in the Human Genome Project -- was announced last June at a press
conference at the White House and will be published in the February 15, 2001
issue of "Nature". An
ongoing research challenge is to piece together and analyze the multitudes of
data produced by the Project. NCBI has completed its first assembly of the DNA
sequence into an organized and easily accessible resourc -- including labels
that point to important regions of the sequence such as those containing
genes-and is now making it public. If
you think of the genome as a book, it wasn't "read" from cover to
cover. Instead, it was photocopied and split into paragraphs -- with no spacing
or punctuation -- before being sequenced by various participants in the Human
Genome Project. NCBI scientists are working to put the paragraphs back into
their correct order, annotate them with section headings that guide the reader,
and create an index to help locate any particular section of interest. NCBI's
Web site serves as an integrated, one-stop, genomic resource for biomedical
researchers around the world. Using search and analysis tools developed at NCBI,
scientists can, for example: --find
a gene's location in the genome --find
other genes in the same region --correlate
many diseases to genes --find
out if a similar gene exists in another organism --see
genetic variations The
Human Genome data can be downloaded in its entirety, chromosome by chromosome,
in segments referred to as "contigs" (for "contiguous
sequence"). This data, along with information about the location of genes
and other biological features associated with the sequence, is available from
NCBI's public FTP site. For
more information and sample searches illustrating how NCBI tools can be used for
scientific discovery, see the Introduction to NCBI's Genome Resource or Take a
Tour of the Draft Human Genome, both available http at the address above. |
