mitosis errors practice
instructions: below are different drawings representing mitosis. each of them has at least one error, often several errors. work with your partner/ group to look at each image, then type all errors your group sees in the space provided below each picture.

Explanation:

Step1: Analyze Example A

In Example A's mitosis stages:

• Prophase: Chromosomes should condense, but drawing shows scattered shapes without clear sister chromatids.
• Metaphase: Chromosomes should align at the metaphase plate, but they are not in a single line.
• Anaphase: Sister chromatids should separate to opposite poles, but the drawing shows chromosomes moving incorrectly.
• Telophase: Daughter cells should have identical chromosome sets, but they differ (one has 1 chromosome, the other 2).

Step2: Analyze Example B

In Example B's mitosis stages:

• Prophase: Centrioles should move to opposite poles, but they are not positioned correctly.
• Metaphase: Chromosomes should align at the metaphase plate, but they are not in a single line.
• Anaphase: Sister chromatids should separate, but the drawing shows chromosomes moving to the same pole.
• Telophase: Daughter cells should have identical chromosome sets, but they differ (one has 2 chromosomes, the other 1).

Answer:

Mistakes in Example A:

1. Prophase lacks condensed sister chromatids.
2. Metaphase chromosomes not aligned at metaphase plate.
3. Anaphase sister chromatids not separating properly.
4. Telophase daughter cells have unequal chromosome numbers.

Mistakes in Example B:

1. Prophase centrioles mispositioned.
2. Metaphase chromosomes not aligned at metaphase plate.
3. Anaphase chromosomes moving to same pole.
4. Telophase daughter cells have unequal chromosome numbers.
