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

Front

What occurs during interphase?

Back

Interphase is the longest phase of the cell cycle where the cell grows, performs its normal functions, and prepares for division. It includes G1 (cell growth), S (DNA replication), and G2 (preparation for mitosis).

Front

What is the S phase of the cell cycle?

Back

The S phase (Synthesis phase) is the part of interphase where DNA is replicated, resulting in two identical sets of chromosomes.

Front

What happens during mitosis?

Back

Mitosis is the process of cell division where one cell divides to produce two identical daughter cells. It includes stages: prophase, metaphase, anaphase, and telophase.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of the cell cycle where the cytoplasm of a parental cell divides into two daughter cells, completing the cell division process.

Front

What is the role of the cell plate in plant cell division?

Back

The cell plate is formed during cytokinesis in plant cells and develops into the new cell wall that separates the two daughter cells.

Front

What occurs during metaphase of mitosis?

Back

During metaphase, chromosomes line up along the equator of the cell, and spindle fibers attach to the centromeres of the chromosomes.

Front

What is the significance of the G1 phase?

Back

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

Front

What happens during anaphase?

Back

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

Front

What is the difference between mitosis and cytokinesis?

Back

Mitosis is the division of the nucleus, while cytokinesis is the division of the cytoplasm, resulting in two separate cells.
