Open Ended

Explain the significance of the S phase in the cell cycle.

Multiple Choice

What occurs during the G2 phase of the cell cycle?

• Cell growth continues and centrosomes are fully replicated

• DNA is replicated

• Chromosomes align at the metaphase plate

• The cell divides into two daughter cells

Open Ended

Explain the significance of the G2 phase in preparing a cell for mitosis.

Multiple Choice

What is the main purpose of mitosis?

• To distribute replicated DNA to two daughter cells

• To replicate DNA

• To carry out cellular respiration

Multiple Select

Which of the following statements about mitosis are correct?

• It is a continuous process

• It has four phases

• It takes about two hours or less

• It occurs only in prokaryotes

Multiple Choice

During prophase, what happens to chromatin fibers?

• They condense and shorten into chromosomes

• They are replicated

• They are destroyed

• They move to opposite poles

Multiple Choice

What is the difference between a chromatid and chromatin?

• Chromatid is a single DNA strand, while chromatin is the material chromosomes are made of

• Chromatid is found only in bacteria, chromatin is found in all cells

• Chromatid contains RNA, chromatin does not

• Chromatid is a protein, chromatin is a carbohydrate

Multiple Choice

Which of the following best describes the function of a chromosome?

• A thread-like structure carrying genetic information in the form of genes

• A segment of DNA that codes for a trait

• A structure that holds two chromatids together

• A material composed only of proteins

Open Ended

Explain the relationship between chromosomes, chromatids, and genes as shown in the diagram.

Multiple Select

Select all the correct statements about the events that occur during prophase.

• The central centromere holds the pairs together

• The mitotic spindle pushes centrioles apart

• The nuclear membrane fragments and disperses to the ER

• Chromosomes are duplicated

Multiple Choice

Which of the following statements about the mitotic spindle during prophase is correct?

• It pushes centrioles farther apart towards opposite ends of the cell

• It fragments the nuclear membrane

• It holds chromatids together

• It interacts with the ER

Multiple Choice

The ___________ holds the replicated sister chromatids together.

• centriole
• chromosomes
• centromere
• cycles

Multiple Choice

Structure (b) is a ____.

• chromosome
• chromatid
• centromere

Multiple Choice

Which phase of the cell cycle is #5?

• Interphase

• Prophase

• Anaphase

• Metaphase

Multiple Choice

Which Image represents Anaphase?

Multiple Choice

Which Image represents Telophase?

Multiple Choice

What happens during cytokinesis?

• The nucleus disappears

• The cell membrane divides

• The DNA divides

• Two new nuclei form

Multiple Choice

What is Cytokinesis?

• structure that holds the sister chromatids together.

• the phase of the cell cycle in which the nucleus and its contents divide.

• the phase in which the cytoplasm and its contents divide.

• the period during the cell cycle of a cell’s growth and development.

Multiple Choice

What might happen if cytokinesis did not occur after mitosis?

• The cell becomes stronger because it has two sets of organelles.

• The cell becomes heavier because it has two sets of organelles.

• The cells would remain fused together and the new double cell would have duplicates of all parts.

• The cell becomes bigger because it has two sets of organelles.
