Cell Cycle Practice Flashcard

Front

What is the cell cycle?

Back

The cell cycle is the series of events that take place in a cell leading to its division and duplication (replication). It consists of phases: interphase, mitosis, and cytokinesis.

Front

What happens during Interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division. It includes G1 (cell growth), S (DNA synthesis), and G2 (preparation for mitosis).

Front

What is Mitosis?

Back

Mitosis is the process of cell division where a single cell divides to produce two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What are the phases of Mitosis?

Back

The phases of mitosis are Prophase, Metaphase, Anaphase, and Telophase.

Front

What occurs during Prophase?

Back

During Prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the spindle apparatus begins to form.

Front

What occurs during Metaphase?

Back

During Metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes.

Front

What occurs during Anaphase?

Back

During Anaphase, sister chromatids are pulled apart to opposite poles of the cell, ensuring each daughter cell will receive an identical set of chromosomes.

Front

What occurs during Telophase?

Back

During Telophase, the chromosomes uncoil back into chromatin, the nuclear envelope re-forms around each set of chromosomes, and the spindle apparatus disassembles.

Front

What is Cytokinesis?

Back

Cytokinesis is the final step of cell division where the cytoplasm divides, resulting in two separate daughter cells.

Front

How many chromosomes do daughter cells have after mitosis if the parent cell has 4 chromosomes?

Back

Each daughter cell will have 4 chromosomes, identical to the parent cell.
