Applications and Proposed Benefits
Potential benefits of sequencing the human genome expand to many fields from molecular medicine to a better understanding of human evolution. The Human Genome Project through its sequencing of the DNA can help us understand diseases including genotyping of specific viruses to direct appropriate treatment; identification of oncogenes and mutations linked to different forms of cancer; designing medications and predicting its response better; advancement in forensic applied sciences; biofuels and other energy applications; agriculture, livestock breeding, bioprocessing; risk assessment; bioarcheology, anthropology, evolution. Another proposed benefit is the commercial development of genomics research related to DNA based products, a multibillion dollar industry.
The sequence of the DNA is stored in databases available to anyone on the Internet. The U.S. National Center for Biotechnology Information (and sister organizations in Europe and Japan) house the gene sequence in a database known as GenBank, along with sequences of known and hypothetical genes and proteins. Other organizations, such as the Genome Bioinformatics Group at the University of California, Santa Cruz, and Ensembl present additional data and annotation and powerful tools for visualizing and searching it. Computer programs have been developed to analyze the data, because the data itself is difficult to interpret without such programs.
The process of identifying the boundaries between genes and other features in a raw DNA sequence is called genome annotation and is the domain of bioinformatics. While expert biologists make the best annotators, their work proceeds slowly, and computer programs are increasingly used to meet the high-throughput demands of genome sequencing projects. The best current technologies for annotation make use of statistical models that take advantage of parallels between DNA sequences and human language, using concepts from computer science such as formal grammars.
All humans have unique gene sequences. Therefore the data published by the HGP does not represent the exact sequence of every individual's genome. It is the combined "reference genome" of a small number of anonymous donors. The HGP genome is a scaffold for future work in identifying differences among individuals. Most of the current effort in identifying differences among individuals involves single-nucleotide polymorphisms and the HapMap.

Famous quotes containing the words proposed and/or benefits:
“It is not always possible to predict the response of a doting Jewish mother. Witness the occasion on which the late piano virtuoso Oscar Levant telephoned his mother with some important news. He had proposed to his beloved and been accepted. Replied Mother Levant: “Good, Oscar, I’m happy to hear it. But did you practice today?””
—Liz Smith (20th century)
“It is too late in the century for women who have received the benefits of co-education in schools and colleges, and who bear their full share in the world’s work, not to care who make the laws, who expound and who administer them.”
—J. Ellen Foster (1840–1910)
