What kind of research can be done with genomic data?
Determine the function of genes and the elements that regulate genes
throughout the genome.
Find variations in the DNA sequence among people and determine their
significance. The most common type of genetic variation is known as a
single nucleotide polymorphism or SNP (pronounced “snip”).  These
small differences may help predict a person’s risk of particular
diseases and response to certain medications.
Discover the 3-dimensional structures of proteins and identify their
functions.
Explore how DNA and proteins interact with one another and with the
environment to create complex living systems.
Develop and apply genome-based strategies for the early detection,
diagnosis, and treatment of disease.
Sequence the genomes of other organisms, such as the rat, cow, and
chimpanzee, in order to compare similar genes between species.
Develop new technologies to study genes and DNA on a large scale and
store genomic data efficiently.
Continue to explore the ethical, legal, and social issues raised by
genomic research.
