EDIT-027 Final Project
Overview
This is EDIT-027 Final Project
Human Biology
Topic:
Mitosis
Assessment:
A short answer assessment that demonstrates the understanding of mitosis
Student Learning Outcomes:
- Describe the stages of mitosis.
- Describe the movement of chromosomes and chromatids during mitosis.
- Determine the chromosome content of cells during various stages given information about the n or 2n number of the cell.
Description:
I have adapted the figure of mitosis from OpenStax. I have transformed it by writing the description of mitosis before the figure.
What is mitosis?
Mitosis is a type of cell division that happens in all cells of our body. It is a process that allows for the growth, repair, and replacement of cells in multicellular organisms. Mitosis is when a cell divides to produce two identical cells genetically identical to the parent cell. Mitosis consists of several steps that are illustrated below.
Figure 6.4 Animal cell mitosis is divided into five stages—prophase, prometaphase, metaphase, anaphase, and telophase—visualized here by light microscopy with fluorescence. Mitosis is usually accompanied by cytokinesis, shown here by a transmission electron microscope.

Assessment:
- During which phase of mitosis do we have twice as many chromosomes?
- If a cell has 20 chromosomes (total), how many chromosomes will be present during the metaphase of mitosis? During anaphase? In the two daughter cells?
- An organism has 7 pairs of chromosomes. How many chromosomes are present during metaphase? During anaphase? In the cells that have completed mitosis.
- An organism has 15 chromosomes in its somatic cells. The cell undergoes mitosis but cytokinesis fails to happen. How many chromosomes are present in the cell?
