Cell Cycle and Mitosis Review

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 interphase and the mitotic phase.

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (G1, S, G2) and the Mitotic phase (M phase, which includes mitosis and cytokinesis).

Front

What happens during interphase?

Back

During interphase, the cell grows, duplicates its DNA, and prepares for mitosis. It consists of three sub-phases: G1 (cell growth), S (DNA synthesis), and G2 (preparation for mitosis).

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

What is cytokinesis?

Back

Cytokinesis is the process during cell division where the cytoplasm divides, resulting in two separate daughter cells.

Front

What is the purpose of DNA replication before mitosis?

Back

The purpose of DNA replication before mitosis is to ensure that each daughter cell receives an identical set of chromosomes.

Front

What are chromosomes?

Back

Chromosomes are long, thread-like structures made of DNA and proteins that contain genetic information.

Front

What is the significance of the number of chromosomes in a cell?

Back

The number of chromosomes in a cell is crucial for maintaining genetic stability and ensuring proper cell function and division.

Front

What occurs during prophase?

Back

During prophase, chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What happens during metaphase?

Back

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