Stages of Mitosis Flashcards

Questions and Answers

What is the stage where the cell grows and functions, and the DNA duplicates?

Metaphase

Interphase (correct)

Prophase

Anaphase

What happens during Prophase?

The nuclear membrane breaks down, chromosomes are clearly visible, and the spindle begins to form.

What occurs during Metaphase?

Chromosomes are lined up in the center of the cell.

What is the definition of Anaphase?

The pairs of chromatids that make up the chromosomes separate from each other and are pulled to two opposite ends of the cell. Signup and view all the answers

What happens during Telophase?

Nuclear membranes form around both sets of chromosomes and the chromosomes uncoil. The cytoplasm starts separating. Signup and view all the answers

What is Cytokinesis?

It's the division of the cell's cytoplasm. Signup and view all the answers

Study Notes

Interphase

The cell undergoes growth and normal functions.
DNA replication occurs, ensuring each daughter cell gets identical genetic information.
The nucleus remains clearly visible, indicating active cellular processes.

Prophase

The nuclear membrane disintegrates, allowing access to the chromosomes.
Chromosomes condense and become distinctly visible under a microscope.
Formation of the spindle apparatus begins, which is crucial for chromosome movement.

Metaphase

Chromosomes align in the cell equator, known as the metaphase plate.
This alignment ensures that each sister chromatid will be equally distributed to each daughter cell.

Anaphase

Sister chromatids separate and move toward opposite poles of the cell.
This movement is facilitated by the spindle fibers, ensuring proper segregation of chromosomes.

Telophase

Nuclear membranes reform around each set of separated chromosomes, creating two distinct nuclei.
Chromosomes begin to uncoil, reverting to a less condensed chromatin state.

Cytokinesis

This process occurs alongside Telophase and involves the division of the cytoplasm.
Not considered a phase of mitosis, but essential for the complete separation of daughter cells.
