Cell Cycle

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).

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 (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. It includes four main stages: 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 mitotic spindle begins to form.

Front

What occurs during metaphase?

Back

During metaphase, chromosomes line up 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 and move toward opposite poles of the cell.

Front

What occurs during telophase?

Back

During telophase, the chromosomes reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense.

Front

How many phases are there in mitosis?

Back

There are four phases in mitosis: prophase, metaphase, anaphase, and telophase.

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm of a parental cell is divided into two daughter cells.
