McGraw Hill Stages of Mitosis Quiz

Mitosis Stages

• Sister chromatids separate and move to opposite poles during anaphase.
• The main event in prometaphase is the breakdown of the nuclear envelope.
• Metaphase involves the alignment of chromosomes at the cell equator.
• In telophase, chromosomes uncoil and a nuclear envelope forms around each group of chromatids.
• Chromosomes condense and become visible during prophase.
• During prophase, centrosomes move towards opposite poles, characterized by the formation of a spindle apparatus.
• Cytokinesis typically begins during telophase.

Meiosis

• Prophase I involves the independent alignment of homologs and crossing-over.

Mitosis Events

• During prometaphase, the nuclear envelope breaks down, and microtubules from opposite poles attach to the sister chromatids.
• In anaphase, the centromeres divide, and sister chromatids move to opposite poles.
• In metaphase, the chromosomes align on the metaphase plate.
• In telophase, the nuclear envelope forms around each group of chromatids, and the spindle fibers disappear.
• Sister chromatids segregate to different daughter cells during anaphase.
• The nuclear envelope breaks down during prometaphase.

Test your knowledge on the stages of mitosis as presented in the McGraw Hill material, including prometaphase, breakdown of the nuclear envelope, formation of the mitotic spindle, and attachment of sister chromatids to microtubules.
