  • Ban on genetic discrimination in workplace

    The Americans with disabilities act was signed July 26, 1990. In 1995, the U.S. Equal Employment Opportunity Commission issued a modification on the definition of disability. It stated that the ADA would protect individuals subjected to discrimination on the basis of genetic information relating to illness, disease or other disorders. The U.S. Equal Employment Opportunity Commission did this.
  • Physical Map of Human Genome Completed

    A physical map uses sequence-tagged sites as markers to order large segments of DNA. One of the goals of the HGP was to complete a physical map with a marker every 100,000 base pairs by 1998. The map built by 1995 was a significant milestone toward that goal. it contained 15,086 STSs, spaced an average of 199,000 base pairs apart.
  • International Strategy Meeting on Human Genome Sequencing

    The first international strategy meeting on human genome sequencing drew scientists from the countries in Europe, North America, and Asia funding human genome sequencing projects. The scientists gathered to compare sequencing strategies and to discuss guidelines for data release.
  • Human Gene Map Created

    Scientists created a map showing the locations of ESTs representing fragments of more than 16,000 genes from throughout the genome.
  • Human DNA Sequence Begins

    In 1996, the National Human Genome Research Institute funded pilot projects to find efficient strategies for completely sequencing the human genome. The pilot projects tested the feasibility of large-scale sequencing, and explored how accurate and how costly alternative approaches might be.
  • Recommendations on Genetic Testing

    A Task Force on Genetic Testing was created by the NIH-DOE Working Group on Ethical, Legal, and Social Implications of Human Genome Research to review genetic testing in the United States and make recommendations to ensure the development of safe and effective genetic tests. The task force declared that safe assured quality but it should also be used by laboratories. The task force also made sure it was safe to release the test when they are safe.
  • HGP Map Included 30,000 Human Genes

    In October 1998, HGP researchers released a gene map that included 30,000 human genes, estimated to represent approximately one-third of the total human genes.
  • Genome of Roundworm C. elegans Sequenced

    In December 1998, the first genome sequence of a multicellular organism, the roundworm Caenorhabditis elegans, was completed. C. elegans measures one millimeter in length and lives in dirt. It was the first animal complete with nervous and digestive systems and a system for reproducing sexually to have its genome deciphered. Also, like humans and other animals, C. elegans begins life as a single fertilized cell and passes through a precise program of embryonic development.
  • Full-scale Human Genome Sequencing

    In March 1999, HGP participants advanced their goal of obtaining draft sequence covering 90 percent of the human genome to 2000, a year and a half before projected previously. Full-scale human genome sequencing began.
  • Chromosome 22

    In December 1999, the HGP completed the first finished, full-length sequence of a human chromosome, chromosome 22. In the clone by clone approach, clones of human DNA, such as bacterial artificial chromosomes , that have a precisely known location on a physical map are the starting points for DNA sequencing reactions.
  • Free Access to Genomic Information

    In March 2000, U.S. President Clinton and U.K. Prime Minister Tony Blair stated that raw, fundamental data about human genome sequence and its variations should be freely available. They agreed that the best course of action would be to urge the following: First, that raw fundamental sequence data - the letters that make up the book of human life - be distributed as widely as possible without barriers to its use.
  • First Draft of the Human Genome Sequence Released

    The draft sequence covered more than 90 percent of the human genome. One surprise is that the estimated number of genes was lower than expected, just 30,000-35,000. The sequence data was immediately and freely released to the world.
  • Researchers Find Genetic Variation Associated with Prostate Cancer

    Researchers identified a gene on chromosome 1 associated with a hereditary form of prostate cancer. Previously, the researchers had studied families with high risks for prostate cancer and identified regions of chromosomes 1, 17, 20, and X as being associated with the higher risk. The work was a collaboration between researchers at the National Human Genome Research Institute, Johns Hopkins Medical Institutions, and The Cleveland Clinic.
  • Human Genome Project Completed

    The primary goal of the project was to produce a reference sequence of the human genome. The finished sequence announced by the international consortium covers 99 percent of the genome and is accurate to 99.99 percent.
  • The fiftieth anniversary of Watson and Crick's Description of the Double Helix

    In April 1953, a paper appeared in the journal Nature that proposed a double helix structure for deoxyribose nucleic acid DNA. The structure was deceptively simple and immediately answered some important questions about genes and how they work.
  • The First National DNA Day Celebrated

    The United States Congress passed a resolution setting aside April 25th as National DNA Day. The date was chosen to mark the 50th anniversary of the publication of the landmark paper by Francis Crick and James Watson describing the double helix model of DNA and the recent official completion of the Human Genome Project. On this day, a series of events unfolded across the country all having to do with the discovery of DNA and its impacts on science and society.
