Presentation on theme: "Contributors to the Discovery of DNA Webquest"— Presentation transcript:
1Contributors to the Discovery of DNA Webquest The work, discoveries, and scientists involved in the history of DNA.
2The MissionYou just got hired as a scientist in a genetics laboratory. As your first assignment approaches, you want to brush up on your history of DNA. You decide to research the following:The scientists involved in the discovery of DNA.The discoveries and research that led to the realization that DNA was the genetic material.The scientists who were involved in discovering the structure of DNA.
3The MissionYou will compile a dossier on the scientists involved as well as their research and what it meant. You research the following scientists on the next slides. With each scientist/s is a list of internet sites you can search for information. Follow along on your concept map to collect the main ideas. Remember you only have one period!
4DOSSIER For each scientist/s, find the following information: The date of their discovery/research.Their discovery or contribution to DNA history.How they come to this discoveryExample: method, DNA technology, process, or model.Remember, you do not need to visit each website for each scientist. Just find the information you need for each scientist.
5Frederick Griffith Websites: DNA Transformation Slideshow of Griffith's Research (Use Slides 7-12)Animation of Griffith’s experimentPoints to Remember:What was the name of Griffith’s discovery?What did his discovery show?
6Oswald Avery Websites: Avery and the transforming principle Avery on the Genetics TimelinePoints to Remember:What was Avery trying to find out?What did Avery finally realize about transformation?
7Alfred Hershey and Martha Chase Websites:Diagram of Hershey-Chase experimentDescription of ExperimentInteractive Simulation of ExperimentAnother good diagram with descriptionPoints to Remember:What did Hershey and Chase use in their experiment to transfer genetic information?What two parts of the virus were being tested in their experiment?What did Hershey and Chase conclude?
8Erwin Chargaff Websites: Chargaff's Rules Description of Chargaff's RulesPoints to Remember:What are Chargaff’s rules?What did the similarities in base pairing between different organisms say about DNA?
9Rosalind Franklin and Maurice Wilkins Websites:Rosalind's ResearchMore Rosalind InformationInformation on Maurice Wilkins and his work with DNAPoints to RememberWhat technique did Rosalind and Maurice use in their research?What did Rosalind and Maurice’s work help show about DNA?
10Francis Crick and James Watson WebsitesPeople and Discoveries: Watson and CrickDNA Structure ContributorsA look back at DNA 50 years laterPoints to Remember:What was the name given to Watson & Crick’s structure of DNA?What did their model of DNA help explain about DNA?
11Mission Accomplished!You’re done! Once you have completed your dossiers, turn them in.
