Mitosis is the stage of the cell cycle during which

• the cell’s nucleus divides into two new nuclei.

• the cell’s DNA is replicated.

• the cell divides into two new cells.

• the cell’s cytoplasm divides.

During what stage of the cell cycle does replication occur?

• interphase

• cytokinesis

• prophase

• mitosis

The regular cycle of growth and division that cells undergo is called

• replication.

• the cell cycle.

• interphase.

• mitosis.

Under which of the following conditions is lactic-acid fermentation most likely to occur?

• a very fast run

• a long walk

• sleeping

• playing video games

What is copied during replication?

• the cell’s organelles

• chromosomes

• the cell’s DNA

• two daughter cells

The stage of respiration that releases most of the energy in glucose occurs in the

• nucleus.

• chloroplast.

• cytoplasm.

• mitochondria.

What happens during cytokinesis in animal cells?

• A new round of mitosis begins.

• Two new daughter cells are formed.

• Each organelle divides into two parts.

• A cell plate forms in the middle of the cell.
