Challenged the idea that a higher being created life. Propose Life changes over time through natural selection
-
Through his work on pea plants discover traits were passed on from
parents through “factors”. There was a question.What are
these factors? -
Friedrich Miescher discovered DNA itself through his studying of white blood cells when after the experiment there’s was snotty gray stuff of biological substance he called nucleic but didn’t know it’s role or what it look like
-
These man are known for the George Beadle and Edward Tatum experiment as it proved that genes are responsible for giving the directions needed to produce enzymes that control metabolic processes.
-
Chargaff discovered the pairing Rules of DNA letters, noticing that A Matches to T, and C to G.
-
Used bacteriophage (a virus) to prove that DNA
was the hereditary material -
She was crucial as she contributed to the solution of the structure of DNA as her images X-rays of DNA put Watson and Crick towards the right structure
-
He led the way in working out the structure of biological
molecules. He suggested that DNA was a triple helix. -
They discover the double helix, the twisted-ladder structure of deoxyribonucleic acid (DNA). Not triple.
-
Maurice Wilkins initiated the experimental research into DNA that culminated in Watson and Crick’s discovery of its structure in 1953.
-
The U.S. Equal Employment Opportunity Commission extended workplace protections under the Americans with Disabilities Act to cover discrimination based on genetic information.
-
One of the goals of the HGP was to complete a physical map with a marker every 100,000 base pairs by 1998. A physical map uses sequence-tagged sites (STSs) as markers to order large segments of DNA. It contained 15,086 STSs, spaced an average of 199,000 base pairs apart.
-
The scientists gathered to compare sequencing strategies and to discuss guidelines for data release. The attendees agreed that all human sequence data they produce should be made freely available to the public.
-
Scientists created a map showing the locations of ESTs (expressed sequence tags) representing fragments of more than 16,000 genes from throughout the genome.
-
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.
-
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.
-
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.
-
In December 1998, the first genome sequence of a multicellular organism, the roundworm Caenorhabditis elegans, was completed.
-
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.
-
In December 1999, the HGP completed the first finished, full-length sequence of a human chromosome - chromosome 22. This accomplishment demonstrated the power of the HGP method of clone-by-clone sequencing to obtain large amounts of highly accurate sequence.
-
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.
-
The Human Genome Project international consortium published a first draft and initial analysis of the human genome sequence.
-
Researchers identified a gene on chromosome 1 associated with a hereditary form of prostate cancer. The work was a collaboration between researchers at the National Human Genome Research Institute, Johns Hopkins Medical Institutions, and The Cleveland Clinic.
-
The International Human Genome Sequencing Consortium announced the successful completion of the Human Genome Project more than two years ahead of schedule and under budget. The primary goal of the project was to produce a reference sequence of the human genome
-
The model proposed by Francis Crick and James Watson resulted from nearly two years of work and was partly based on X-ray diffraction data from their colleagues Maurice Wilkins and Rosalind Franklin. Crick, Watson, and Wilkins shared the 1962 Nobel Prize in Physiology or Medicine for their work.
