Cell Cycle & Mitosis Review

Front

What is the S Phase of the cell cycle?

Back

The S Phase (Synthesis Phase) is the part of the cell cycle where DNA is replicated, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What is interphase in the cell cycle?

Back

Interphase is the longest phase of the cell cycle, during which the cell grows, performs its normal functions, and prepares for division by replicating its DNA.

Front

Why is DNA replication important before cell division?

Back

DNA replication is crucial before cell division to ensure that genetic information is accurately passed on to daughter cells.

Front

Define cancer in the context of cell division.

Back

Cancer is defined as uncontrolled cell division, where cells grow and divide without the normal regulatory mechanisms.

Front

What can uncontrolled cell growth lead to?

Back

Uncontrolled cell growth can lead to cancer, where abnormal cells proliferate uncontrollably.

Front

What happens during the G1 Phase of the cell cycle?

Back

During the G1 Phase (Gap 1 Phase), 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 (Gap 2 Phase) is where the cell continues to grow and prepares for mitosis, ensuring all DNA is replicated and undamaged.

Front

What occurs during mitosis?

Back

Mitosis is the process of cell division where one cell divides to produce two genetically identical daughter cells.

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 significance of checkpoints in the cell cycle?

Back

Checkpoints are regulatory mechanisms that ensure the cell cycle progresses only when conditions are favorable and the DNA is intact.
