Unit 4: Cell Communication & The Cell Cycle Review

Front

What happens if a cell undergoes mitosis without cytokinesis?

Back

The resulting cell will have more than one nucleus.

Front

Where can receptors for signal molecules be found?

Back

Receptors can be found in the plasma membrane and in the cytoplasm/nucleus.

Front

Which of the following is not a cell cycle checkpoint? G1, G2, G0, M?

Back

G0 is not a cell cycle checkpoint.

Front

What does not occur during mitosis?

Back

Replication of DNA does not occur during mitosis.

Front

When is a G protein considered active?

Back

A G protein is active when GTP is bound to it.

Front

What is the role of cytokinesis in cell division?

Back

Cytokinesis is the process that divides the cytoplasm of a parental cell into two daughter cells.

Front

What is the function of the spindle apparatus during mitosis?

Back

The spindle apparatus helps separate sister chromatids during mitosis.

Front

What is the significance of cell cycle checkpoints?

Back

Cell cycle checkpoints ensure that the cell is ready to proceed to the next phase of the cycle, preventing errors.

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 is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.
