Cell Cycle and Mitosis

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 (G1, S, G2 phases) and the mitotic phase (M phase).

Front

What are the main stages of the cell cycle?

Back

The main stages 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, performs its normal functions, and prepares for division. DNA is replicated during the S phase.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of cell division where the cytoplasm of a parental cell is divided into two daughter cells.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA is replicated, resulting in two copies of each chromosome.

Front

What is the role of the G1 phase in the cell cycle?

Back

The G1 phase is the first stage of interphase where the cell grows and synthesizes proteins necessary for DNA replication.

Front

What is the role of the G2 phase in the cell cycle?

Back

The G2 phase is the second stage of interphase where the cell continues to grow and prepares for mitosis.

Front

What happens 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.
