A friend is preparing a model of mitosis for a science project. The goal of the project is to demonstrate how the cell uses mitosis to separate the DNA into the daughter cells. They have decided to only include the chromosomes in their model.

Identify the explanation below that you would use to encourage your friend to change their approach for completing the project.

  1. The process that changes the DNA of cells in order to make them become more specialized in structure and function is differentiation.

  2. The process that occurs when the cell leaves the cell cycle but still carries out the normal functions is senescence.

  3. The explanation to encourage your friend to change their approach for completing the project would be: There are aspects of mitosis that would be better understood by including specific organelles.
