Unit 7.2 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 phases: G1, S, G2, and M.

Front

What happens during the G1 phase of the cell cycle?

Back

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

Front

What occurs 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 G2 phase?

Back

The G2 phase is the period after DNA replication where the cell prepares for mitosis, including further growth and organelle duplication.

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 is cytokinesis?

Back

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

Front

What is the result of the cell cycle?

Back

The result of the cell cycle is two identical daughter cells.

Front

Why is the cell cycle important for organisms?

Back

The cell cycle allows organisms to grow, develop, and repair damaged tissues.

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints are regulatory mechanisms that ensure the proper progression of the cell cycle and prevent errors such as DNA damage.

Front

What happens if a cell fails to undergo apoptosis?

Back

If a cell fails to undergo apoptosis, it may lead to uncontrolled cell growth, which can result in cancer.
