DOK Level 1: Recall

What is the role of cyclins in the regulation of the cell cycle?

• They degrade DNA

• They promote cell division

• They prevent chromosome segregation

• They enlarge the cell size

DOK Level 2: Skill/Concept

How does mitosis differ from meiosis in terms of genetic diversity?

• Mitosis results in genetically identical cells, while meiosis results in genetically diverse cells.

• Mitosis results in genetically diverse cells, while meiosis results in genetically identical cells.

• Both processes result in genetically identical cells.

• Both processes result in genetically diverse cells.

DOK Level 2: Skill/Concept

Explain how the mitotic spindle contributes to the accuracy of chromosome segregation.

• It prevents DNA replication errors.

• It ensures chromosomes attach at the correct location on the spindle.

• It synthesizes new DNA strands.

• It enlarges the nuclear envelope.

DOK Level 2: Skill/Concept

What mechanism ensures that each new cell receives an exact copy of the chromosomes during mitosis?

• Cytokinesis

• Chromosomal segregation

• DNA replication

• Nuclear envelope breakdown

Tags

DOK Level 2: Skill/Concept

Describe the role of checkpoints in the cell cycle regulation.

• They speed up the cell cycle.

• They ensure that each stage of the cell cycle is completed accurately before the next stage begins.

• They decrease the accuracy of DNA replication.

• They eliminate the need for cyclins.

DOK Level 3: Strategic Thinking

How does the cell ensure that mitosis and cytokinesis occur in the correct sequence?

• By random chance

• Through the action of motor proteins

• By the sequential activation and deactivation of cyclins and cyclin-dependent kinases

• By increasing the cell volume
