Question

1. what happens to the sister chromatids during mitosis?
2. correctly label the stages of mitosis in the cell cycle below.
3. phases

a. prophase: this is the & phase of mitosis

• chromatin, & the nuclear membrane
• centrioles near the nucleus and a starts to form between them.

b. metaphase:

• the spindle fibers
• the sister chromatids known as the, also
• the spindle fibers ensure that

Explanation:

1. During mitosis, sister chromatids separate and move to opposite poles of the cell during anaphase. This ensures that each new daughter - cell receives an identical set of genetic material.
2. The stages of mitosis in order are prophase, metaphase, anaphase, and telophase. Prophase is the first and longest phase where chromatin condenses into chromosomes and the nuclear membrane breaks down. Metaphase is when chromosomes line up in the middle of the cell. Anaphase is when sister chromatids separate. Telophase is the final phase where the nuclear membrane reforms around the separated chromosomes.
3. A. Prophase: This is the first & longest phase of mitosis. Chromatin condenses into chromosomes, & the nuclear membrane breaks down. Centrioles near the nucleus move to opposite poles and a spindle fiber starts to form between them. B. Metaphase: The spindle fibers attach to the centromeres. The sister chromatids, also known as the chromosomes, line up along the equator (middle) of the cell. The spindle fibers ensure that the chromosomes are properly aligned for equal distribution to the daughter cells.

Answer:

1. Sister chromatids separate during anaphase of mitosis and move to opposite poles of the cell.
2. Stages (in order around the cycle): Prophase, Metaphase, Anaphase, Telophase.
3. A. first; longest; condenses into chromosomes; breaks down; move to opposite poles; spindle fiber

B. attach to the centromeres; line up along the equator of the cell; chromosomes; the chromosomes are properly aligned for equal distribution to the daughter cells
