Telophase

Definition

Telophase is the final stage of mitosis, where two daughter nuclei form in a cell. Chromosomes decondense and the nuclear envelope reappears around each set of chromosomes.

5 Must Know Facts For Your Next Test

1. During telophase, the chromosomes that were tightly coiled and visible begin to uncoil and return to their less condensed state.
2. The nuclear envelopes reform around each set of separated sister chromatids now called daughter chromosomes.
3. Telophase is often concurrent with cytokinesis, which divides the cytoplasm of the parental cell into two daughter cells.
4. The mitotic spindle breaks down during this phase, allowing the nucleus to re-establish its structure.
5. Nucleoli reappear within the newly formed nuclei as telophase progresses.

Prophase:

The first stage of mitosis where chromatin condenses into visible chromosomes and the mitotic spindle begins to form.

Metaphase:

The stage of mitosis where chromosomes line up at the cell's equatorial plate, ensuring equal distribution between daughter cells.

Anaphase:

The stage of mitosis following metaphase, where sister chromatids are pulled apart toward opposite poles of the cell by spindle fibers.
