a New Frontier
maps help scientists find their way around in an organism's
genome -- all of its genetic material. These maps are not nearly
as detailed as a road map, or a genome sequence with its thousands
to billions of letters, but they can aid scientists by pointing
out areas for further exploration.
affected by certain kinds of hereditary diseases, for example,
will demonstrate certain features in their
genome maps that serve as "landmarks" or "gene markers"
for that disease.
parts of a genome map may be very detailed and
complete, while other areas are relatively uncharted. As scientists
keep exploring the genome, learning more about the genes in
an organism, the map will become more accurate and detailed.
