What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to divide and replicate. It includes interphase and the M phase.

Front

What are the two major phases of the cell cycle?

Back

The two major phases of the cell cycle are Interphase and the M phase.

Front

What occurs during Interphase?

Back

Interphase is divided into three phases: G1 (cell growth), S (DNA synthesis), and G2 (preparation for mitosis).

Front

What is the G0 phase?

Back

The G0 phase is a resting state where cells exit the cell cycle and do not actively divide.

What is a characteristic of cancerous cells?

Back

Cancerous cells are often irregularly shaped and may have less cytoplasm compared to normal cells.

Front

What is the M phase?

Back

The M phase is the part of the cell cycle where mitosis and cytokinesis occur, leading to cell division.

Front

What is the G1 phase?

Back

The G1 phase is the first phase of interphase where the cell grows and prepares for DNA replication.

Front

What is the S phase?

Back

The S phase is the phase of interphase where DNA is replicated, resulting in two copies of each chromosome.

Front

What is the G2 phase?

Back

The G2 phase is the second growth phase of interphase where the cell prepares for mitosis.

Front

What is the significance of the cell cycle checkpoints?

Back

Cell cycle checkpoints are mechanisms that ensure the cell is ready to proceed to the next phase, preventing errors that could lead to cancer.
