: the spindle is complete, and the chromosomes, attached to microtubules at their kinetochores, are all at the plate.target 1 of 5

Question

Blank: discrete chromosomes are now visible; each consists of two aligned, identical sister chromatids. Later the nuclear envelope will fragment.target 2 of 5
Blank: the chromatids of each chromosome have separated, and the daughter chromosomes are moving to the ends of the cell as their kinetochore microtubules shorten.target 3 of 5
Blank: the chromosomes are condensing and the nucleolus is beginning to disappear. The mitotic spindle is starting to form.target 4 of 5
Blank: daughter nuclei are forming. Cytokinesis has started: The cell plate, which will divide the cytoplasm in two, is growing toward the perimeter of the parent cell.

Answer 1

It looks like you're describing the stages of mitosis. Here's how you can fill in the blanks with appropriate terms for each stage:

1. Metaphase: The spindle is complete, and the chromosomes, attached to microtubules at their kinetochores, are all at the plate.

2. Prophase: Discrete chromosomes are now visible; each consists of two aligned, identical sister chromatids. Later the nuclear envelope will fragment.

3. Anaphase: The chromatids of each chromosome have separated, and the daughter chromosomes are moving to the ends of the cell as their kinetochore microtubules shorten.

4. Prometaphase: The chromosomes are condensing and the nucleolus is beginning to disappear. The mitotic spindle is starting to form.

5. Telophase: Daughter nuclei are forming. Cytokinesis has started: The cell plate, which will divide the cytoplasm in two, is growing toward the perimeter of the parent cell.

These descriptions correctly outline the key events that occur during each phase of mitosis.
