Below are sample questions representative of the exercises included on this worksheet and related 10.47 Cell Cycle Phases and Regulation skill assessments:

Problem 1Difficulty: Mastery

Which synthesis best connects cell-cycle phases and regulation to the needs of a multicellular organism?

ACells should skip checkpoints so damaged cells can divide faster during development.

BMitosis should halve chromosome number whenever tissues need repair.

CCytokinesis alone is enough for growth because DNA does not need copying.

DCells must copy DNA, divide chromosomes, split cytoplasm, and respond to checkpoints so growth and repair occur without uncontrolled proliferation.

Solution & Explanation:Growth and repair require coordinated DNA replication, mitosis, cytokinesis, and regulation. Checkpoints help maintain genetic stability and limit uncontrolled division.

Problem 2Difficulty: Mastery

A tumor sample contains cells with many different chromosome numbers, and sequencing shows a mutation in a spindle-checkpoint gene. Which explanation best connects the evidence?

AThe checkpoint mutation intentionally creates useful chromosome variation.

BChromosome-number differences prove DNA replication never occurred.

CCheckpoint failure can cause chromosome mis-segregation, creating chromosomal instability among tumor cells.

DCytokinesis alone removes chromosome-number variation from tumors.

Solution & Explanation:A defective spindle checkpoint can allow cells to divide with improperly attached chromosomes, producing daughter cells with different chromosome numbers.

Problem 3Difficulty: Mastery

If origin-licensing proteins are not removed or inactivated after S phase begins, what problem could occur?

ACells will never be able to enter G1 after cytokinesis.

BSome DNA regions may be replicated more than once in the same cycle.

CChromosomes will separate before spindle fibers attach in every cell.

DThe cytoplasm will divide without any membrane.

Solution & Explanation:Origin licensing prevents DNA from being copied more than once per cycle. Failure to reset licensing can cause re-replication and abnormal DNA copy number.
