AP Biology Unit 4 review

Front

What is the role of cyclin in the cell cycle?

Back

Cyclin interacts with cyclin-dependent kinase (CdK) to initiate the mitotic phase.

Front

List the correct order of the stages in mitosis.

Back

Prophase, Metaphase, Anaphase, Telophase.

Front

Which of the following is NOT a stage of the cell cycle?

Back

Apoptosis is not a stage of the cell cycle.

Front

What happens when a ligand binds to its receptor?

Back

There is a conformational change in the shape of the receptor.

Front

What is the result of mitosis?

Back

Mitosis results in 2 identical diploid cells.

Front

Define mitosis.

Back

Mitosis is the process of cell division that results in two identical daughter cells.

Front

What is the function of CdK in the cell cycle?

Back

CdK (cyclin-dependent kinase) is an enzyme that, when activated by cyclin, helps to regulate the cell cycle.

Front

What occurs during prophase?

Back

During prophase, chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.

Front

What is cytokinesis?

Back

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

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, including DNA replication.
