Cell cycle

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are G1 (cell growth), S (DNA synthesis), G2 (preparation for mitosis), and M (mitosis and cytokinesis).

Front

What happens during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows in size, produces RNA, and synthesizes proteins necessary for DNA replication.

Front

What is the S phase in the cell cycle?

Back

The S phase is the part of the cell cycle where DNA replication occurs, resulting in the duplication of chromosomes.

Front

What occurs during the G2 phase of the cell cycle?

Back

During the G2 phase, the cell continues to grow and prepares for mitosis by producing proteins and organelles.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, involving several stages: prophase, metaphase, anaphase, and telophase.

Front

What is cytokinesis?

Back

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

Front

What is the longest phase of mitosis?

Back

The longest phase of mitosis is prophase.

Front

What happens during prophase?

Back

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

Front

What is anaphase?

Back

Anaphase is the stage of mitosis where sister chromatids are pulled apart to opposite poles of the cell.
