Phase 2 – Dynamic Understanding
► Investigation Three Summary – Lab Goals
In Investigation Three, you analyzed how cells divide and transfer the genetic information contained in DNA from one cell to another. During this Investigation, you:
1. Modeled cell cycle, cell division, and chromosome activity.
2. Modeled pairs of homologous chromosomes and their duplication.
3. Identified and photographed stages of mitosis with a microscope and digital camera.
► Investigation Three Summary – Learning Goals
Through these experiments, you concluded that:
1. A mutation of the DNA in a gene in a single body cell will get copied when the chromosomes duplicate. All of the new body cells formed through mitosis will then have the mutation. If the mutation causes a change in a protein, all cells will produce the mutant protein. If the cells in an organ are producing mutant proteins, the organ may not function properly. Thus, the organism may not function properly.
