Cell Division Quiz

What is one significance of telophase?

• It initiates cell division.

• It restores the nuclear environment for new cells.

• It breaks down the nuclear membrane.

• It condenses chromosomes.

How does anaphase reduce the risk of mutations?

• By duplicating chromosomes

• By separating chromatids

• By forming new cells

• By creating spindle fibers

During which phase do chromosomes align in the middle of the cell?

• Prophase

• Metaphase

• Anaphase

• Telophase

What structure do spindle fibers attach to during metaphase?

• Nucleus

• Ribosome

• Centromere

• Mitochondria

What is the significance of chromosomes aligning properly during metaphase?

• It ensures cell growth.

• It prevents cell division.

• It ensures even chromosome distribution.

• It stops DNA replication.

What error is prevented by the proper alignment of chromosomes during metaphase?

• Unequal chromosome distribution

• DNA mutation

• Protein synthesis error

• Cell membrane rupture

What happens to chromatin during prophase?

• It dissolves completely.

• It condenses into visible chromosomes.

• It remains unchanged.

• It splits into four parts.

Why is the spindle system necessary during prophase?

• For moving chromosomes.

• For producing energy.

• For synthesizing proteins.

• For storing nutrients.

What is the key event during cytokinesis in animal cells?

• Formation of a cell plate

• Formation of a cleavage furrow

• DNA replication

• Chromosome alignment

According to the base-pairing rule, which base pairs with Adenine (A)?
