The Cell Cycle Flashcard

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase (G1, S, G2) and mitosis.

Front

What are the main phases of the cell cycle?

Back

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

Front

What occurs during the G1 phase of the cell cycle?

Back

During G1, the cell grows and synthesizes proteins necessary for DNA replication.

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA is replicated, resulting in two identical sets of chromosomes.

Front

What is the purpose of the G2 phase?

Back

The G2 phase is for further growth and preparation for mitosis, including the synthesis of proteins and organelles.

Front

What is mitosis?

Back

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

Front

What are the stages of mitosis?

Back

The stages of mitosis are prophase, metaphase, anaphase, and telophase.

Front

What is cytokinesis?

Back

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

Front

What is cancer in relation to the cell cycle?

Back

Cancer is characterized by uncontrolled cell division, leading to the formation of tumors.

Front

What is the significance of checkpoints in the cell cycle?

Back

Checkpoints are control mechanisms that ensure the cell cycle progresses correctly and prevents errors such as DNA damage.
