Schedule>
What happens with multiple sets of chromosomes?? || Griffith, Avery, Hershey & Chase; the beginnings of discovery || Crash Course in Chem- to help understand DNA- how all the pieces fit together || Putting it together- compiling what you know to make a molecule! || Putting it together || 2) demonstration (or LAB if possible) of DNA extraction within strawberries 3) discussion of polyploidy in humans (aneuploidy) and nondisjunction within meiosis; to polyploidy in agriculture || 1) powerpoint story-telling, along with a worksheet to help keep focus and take notes || 1) Review of yesterday's material- what about DNA did they discover about how DNA is built? What molecules are involved? 2) Demonstration of hydrogen bonding vs. covalent bonding (bases vs. sugar-phosphate backbone) 3) Explanation upon board of how to figure out H-bonds || 1) Go over hydrogen bond worksheet 2) Draw molecules of A, T, G, C on board as set up for activity on piecing the DNA together - chargaff's rule too! 3) Students work in groups to connect the bases || 1) Review of H-bonding, and A, T, G, C molecules & how they SHOULD connect! 2) Continuation- how does the rest of the molecule fit together?? 3) discussion of sugar-phosphate backbone (if time permits!) ||
