Do a good job. Remember this project is valued at 20 points. Section 1: Instructions for a Human Being 1.How would you describe the appearance of DNA taken from the test tube,? Long strands of molecules looks like strands of cotton 2. How different are we from a banana? 50 genes of a banana are in us 3. How long is the human genome? 3 billion steps long 4.What will being able to sequence the human genome tell us? Human genome can let us know early about diseases such as early risk cancer Section 2: Getting the Letters Out 1.How did the announcer describe the DNA molecule? Secret to life wrote are chemical message all the way through time 2.How genetically the same are any two babies? 99.9% of babies are the same continuous thread 3.How many nucleotides make up the human genome? 3 200 000 000 4.The date for launching the human genome project was __1990______ . 5. How long did it take to find the gene sequence for cystic fibrosis ? 10 years 6. What percentage of the DNA nucleotides is active and important? 1% 7. What helped speed up the sequencing project? It became computerized How fast did it speed up the sequencing? 1,000 every second 8. The DNA sequence was described by Eric Lander as being akin to a parts list 9. Why is it important to know the human genome sequence (all parts, every letter)? Secret of life; DNA tells us if we are at early risk cancer because sometimes 1 single letter can make a difference Section 3: One Wrong Letter 1. Example of a genetic disorder: The name of the disorder is _____Tay-sachs____________ The cause of the disorder: 4 atoms being different; affects nerve cells in the brain What happens because of that change? Blind, cannot eat solid food, seizures as often as 10 times a day What is the eventual outcome of the disorder? Death by the age of 5-7 The disorder is inherited by Parents are the carrier, both parents have to have the mutated gene What population of people carry this gene? Ashkenazi Jews 2. What can be done if you know all the base pairs making up the human? Find out early parents would know what they would be putting their children through Section 4: Sequencing Race Begins 1.Government scientists through it would take how long to sequence the human genome? 15 years 2.How is DNA code read? Chopped by robots and placed in bacteria tagged with colored dyes. Blue C Yellow G Red T Green A 3. Describe the person who set up a private enterprise to sequence the human genome. Loves things that go fast. Drafter by the navy and worked in a naval hospital. 4.Name the company that he started. What does the name mean? Celera Genomics Celera derived from a latin word means speed. 5.Briefly describe the process utilized. Increased the speed of research making Venter believe they could complete the project in two years 6.In 1998, how long did Venter think the project would take? 2 years Section 5: Ramping Up 1. Name the two main labs and who was in charge of the projects. Celera Genomics/Human Genome Project 2.How many different labs were working on the project at that time? Name a few. Baylor College of Medicine, Sanger Project 3. List a few of the problems they faced with the project. New technology that the scientists were not familiar in using. They also had to put together all the
