Students explain that cells continually divide to make more cells for growth and repair. They are shown the balloon and explained that it is a model of a cell. Students are asked: "How do you think animal cell divide?" The teacher twist the balloon into two parts, organelles are included on both sides. They are explainned that as the cell divides, each new cell receives organelles and a copy of genetic information in the form of chromosomes from the parent cell. Full Review »

Students use this activity to simulate the sequencing of gene and to detect the presence of possible genetic defects. They use diagrams that represent bands of nucleotides in order to determine the sequence of a small piece of the CF gene. Students make comparisons between base sequences of pairs of chromosomes from individuals who are not affected by CF and those who are. Full Review »
