1. Students reinforce their knowledge that DNA is the genetic material for all living things by modeling it using toothpicks and gumdrops that represent the four biochemicals (adenine, thiamine, guanine, and cytosine) that pair with each other in a specific pattern, making a double helix. Students will follow directions to answer questions and build a disaccharide, polysaccharide, two proteins, triglyceride, DNA, and ATP using interactive Google Slides. Even before the structure of DNA was solved, studies indicated that the genetic material must have the following properties: be able to store information; be faithfully replicated and be passed on from generation to generation; and allow for changes, and thus evolution, to occur. A pairs with T; G pairs with C 2. Twist your DNA model. (Hint: look back at the second step of the procedure for help.) No other combinations of colors are allowed. Questions about target DNA 1: a. semi-conservative. DNA model making model of dna instructions colour the individual structures on the worksheet as follows: adenine red guanine blue phosphate brown thymine green Using the model they built, students will differentiate between DNA, chromatin (upper grade levels), chromosomes, and genes.
