Human Genome Project-Lesson Notes The Human Genome Project (HGP) was completed in 2003. It was a 13 year project coordinated by the U.S. Department of Energy and the National Institutes of Health. In the early stages of the project Wellcome Trust in the United Kingdom became major partners in the investigation. Later contributions came from Japan, France, Germany, China and other countries. The main goals of the project were Identify all the approximately 20,000-25,000 genes in human DNA Determine sequences of 3 billion base pairs that make up the human DNA Store all of the information into appropriate databases Improve the tools for data analysis Transfer the related technologies to the private sector Address the ethical, legal and social implications arising from the project. Even though the project is now complete analysis of the gathered data will continue for years. During this lesson we will look at the important stages of the HGP. Creating a time line of important discoveries. We will discuss the health, genetics and evolutionary benefits of the HGP Ethical, social and legal issues will be investigated and discussed The information gathered will be used to identify areas open to debate and important data required to justify view points on mapping the human genome. The lesson will begin with a small power point presentation to introduce the concept of gene mapping and the Human Genome Project. Questions will be asked of students to gain insight into their understanding of the HGP. What is the HGP? Where have you heard about it? How has the HGP been presented in the media? What benefits do you think could be gained from mapping the human genome? This lesson will allow students to gather process and interpret information from internet sites in order to gain an understanding of the HGP its uses, benefits and the ethical, legal and social implications associated with analysis and interpretation of the human genome information. At this point students will be provided with a handout outlining the group activities and the worksheet. Each student will be required to read all of the group tasks in order to establish the outcomes of the activity as a whole (this will also prevent students just looking at their task as a single entity). The group research will only take a small portion of the class time (see lesson plan), allowing for power point presentations and posters to be produced. 1 Following the group web quests each of the 6 groups will present their findings in 2 ways Power point presentation Poster display This will allow the students to answer the questions on the worksheet provided and provide 2 ways of covering all aspects of the required information. Other groups can use the poster information to finalise worksheets and gather all of the information related to the topic. The presentations and posters will be presented at the next lesson with 10 minutes provided at the start of the class for finalising work. 2 Resources List -The Human Genome Project Each student will be provided with the handout titled; Human genome Project Group Web Investigation. Laptop computers. Cardboard for posters. Scissors, glue, pipe cleaners, ribbons, buttons, cellophane, craft paper, glitter, ribbon and textas. Biology text- Spotlight Biology Heinemann Biology Master copy of web site home pages Newspaper articles Question and answer sheet to complete during power point presentations. 3 The Human Story- Group Web Investigation “The Human Genome Project” o Process information from secondary sources to outline the purpose of The Human Genome Project (HGP) and briefly discuss its implications (outcome H12.4). o Students will form into 6 groups of 4 (based on 24 students). o Each group will have a different task as set out below. o At the completion of the investigation each group will; 1. Present their findings to the entire class as a power point presentation including references. 2. Submit a poster detailing the important findings from your investigation. This will include drawings, photos and short summaries in writing (be creative with your design craft supplies are provided including glue, scissors, pipe cleaners, craft paper, cellophane, glitter, ribbon, wool, buttons and textas). o The power point presentations will be performed next lesson. o Web sites for the investigation are listed however; you are entitled to access other appropriate web sites, books or secondary sources.

This will ensure that your group does not overlap or repeat information required by a different group. GROUP 1- What is the Human Genome Project (HGP)? Provide the class with an overview of the HGP. Discuss the background information for establishing this world wide project. Discuss where and when the project started, important findings and current status. GROUP 2- Formulate a timeline including the major events which led to the gene map which is available today. GROUP 3- Discuss the overall benefits of the HGP for world genetics. GROUP 4- Discuss the overall benefits of the HGP for evolution. GROUP 5- Discuss the overall benefits of the HGP for human health. Include major genetic discoveries and link them to benefits for medical research. GROUP 6- Discuss the main ethical, legal, and social implications which arise from the HGP. Present all 3 (ethical, legal and social) in your presentations. Question Sheet provided to complete as the power point presentations are performed (see over). 5 Question sheet-The Human Genome Project Teacher copy with potential answers (complete during the web investigations or during power point presentations and by gathering information from the final group posters displayed around the room). 1. Briefly describe The Human Genome Project. A 13 year project coordinated by the US Department of Energy and the National Institutes of Health to identify all of the genes in Human DNA(approximately 20,000-25,000). To determine the sequences of the 3billion chemical base pairs making up human DNA, store the new information in databases, improve the tools required for analysis, transfer the related technologies to the private sector and address the ethical, legal and social issues which would arise from the project. 2. List the useful websites and texts for revision of this topic. Web sites: National Human Genome Research Institute hhtp://www.genome.gov/25019879 Human Genome Organisation hhtp://www.hugo-international.org/ Human Genome Project Information hhtp://www.ornl.gov/sci/techresources/Human_Genome/home.shtml These sites all have further links for your use. (Heinemann Biology, Spotlight Biology, Web sites provided for the web quest) 3. Provide one ethical issue which may arise from information in the HGP. ( Health funds could potentially make decisions about member criteria based on their DNA and potential genetic diseases) 4. What do scientists need to ensure about the information gained from the HGP. (Genetic information is used for the benefit of humans and no person is being harmed). 6 5. List some of the benefits of mapping the human gene. Include information from your group investigations. (i.e. human health, genetics and evolution). improvements in diagnosing disease, early detection of genetic predisposition to a disease (eg colon cancer, Alzheimer’s and breast cancer), gene therapy, drug design, less disease treatment and more disease prevention. Use biogenics to produce biofuels necessary as fossil fuels decrease. To reduce the likelihood of inheritable mutations. Study of evolution through germ line mutations. Study population migration based on female genetic inheritance. Study sex linked mutations. Crime scene investigation. Match organ donors with recipients for transplants. Determine pedigrees for seed and livestock breeds. To detect bacteria pollutants of air, soil and water. Many more benefits exist. 6. Discuss some of the ethical, legal and social issues arising from obtaining detailed genetic information. Privacy and confidentiality of the information. Who owns it? Fairness of access to the information. Who should have access to the data? Courts, adoption agencies, the military, schools, employers and insurers. Psychological impact i.e. will society form perceptions of individuals with genetic differences? Reproduction, will society make decisions about reproducing based on genetic information? Clinical issues- how will accurate, reliable and useful testing be guaranteed? How do we prepare the public to make informed choices? Uncertainties- some diseases like heart disease are linked to multiple genes. Will this affect decisions about genetic information? Should parents have children tested for old onset diseases? Should the test be performed if there is no available treatment for the disease? 7.
