Prophase
Telophase
Interphase
Metaphase
#8

Which of the following accurately describes the function of centrioles in animal cells during cell division?

They produce spindle fibers
They help in DNA replication
They synthesize proteins
They store genetic information
#9

What is the main difference between cytokinesis in plant cells and animal cells?

Plant cells form a cell plate, while animal cells form a cleavage furrow
Animal cells divide by binary fission, while plant cells divide by mitosis
Animal cells have centrioles, while plant cells do not

#10

Which checkpoint in the cell cycle ensures that DNA is undamaged before proceeding to mitosis?

G1 checkpoint
G2 checkpoint
S checkpoint
M checkpoint
#11

What is the significance of cytokinesis in the cell cycle?

It separates the replicated DNA into two identical daughter cells
It ensures the correct alignment of chromosomes
It initiates DNA replication
It marks the beginning of mitosis
#12

What is the function of cyclins and cyclin-dependent kinases (CDKs) in the regulation of the cell cycle?

They prevent DNA replication
They induce apoptosis
They promote cell division
They inhibit protein synthesis
#13

What is the primary function of the anaphase-promoting complex (APC) during the cell cycle?

To activate cyclin-dependent kinases (CDKs)
To degrade cyclins and trigger exit from mitosis
To initiate DNA replication
To repair DNA damage
#14

What is the consequence of a mutation in a tumor suppressor gene?

Uncontrolled cell division
Apoptosis
Repair of DNA damage
Inhibition of cell division
