DNA Project small medium large DNA PROJECT Assignment: You are going to lead everyone else in class on an imaginary tour through DNA. You are going to have to be clear and concise so that the “tourists” will understand what DNA is and how it is formed. You are also going to need to keep tourist interested so you need to use creativity to design an 3D model of DNA along with a tour Guide to lead everyone thru your model. THIS WILL BE WORTH 100 POINTS!!!!!! DUE DATE:¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬______________________ Instructions: 1. Build a 3 dimensional (3D) model of DNA in a double helix made out of any materials you wish. The size can vary, but it needs to be large enough to be understood with the naked eye from the back of the room as well as small enough to fit through the door. It must be light enough to transport easily. Your model does not need to have detailed chemical structures, but it must contain corresponding and consistent representations for all molecules involved. Your model should include or have: • At least 10 nucleotides on each side • The four different nitrogenous bases (clearly distinguishable from each other) • The different bonds (sugar-phosphate, sugar-nitrogenous base and the hydrogen bonds between the nitrogenous bases) with each bond represented in a different way. • The sugar-phosphate backbone of DNA on each side of the helix- with clear differentiation between the sugar and phosphate • A double helix- your model should be in a double helix when it is on its own. 2. Your must also design a Tour Guide of your DNA. You can use any type of media you choose but it should be no larger than a poster board. It should also be very creative and visual to enhance learning and keep the reader’s attention. This is a GUIDE, not a report. YOU ARE THE TOUR GUIDE! Your tour must correspond to your model. This is not a tour of DNA; it is a tour of YOUR model of DNA. You will take the class on a tour of your DNA on the due date for this project. 3. A bibliography is also required to be on the back of your tour page if you use images or information from a source other than me. GOOD LUCK!!!
