Chapter 12 Test

Before cells can divide, what must be copied?

• Mitochondira

• Cytoplasm

• DNA

• Cell wall

What is the correct order of the cell cycle?

• Interphase, Cytokinesis, Mitosis

• Interphase, Mitosis, Cytokinesis

• Cytokinesis, Mitosis, Interphase

• Anaphase, Telophase, Cytokinesis

Put the following stages of mitosis in order: anaphase, prophase, metaphase, and telophase.

• prophase, metaphase, telophase, anaphase

• prophase, anaphase, metaphase, telophase

• prophase, metaphase, anaphase, telophase

• prophase, telophase, metaphase, anaphase

In mitosis, the two resulting cells are

• different from the starting cell and identical to each other

• different from the starting cell and different from each other

• identical to the starting cell and different from each other

• identical to the starting cell and identical to each other

Why do cells go through mitosis?

• to make food from sunlight

• to create proteins

• to get air into the cells

• to reproduce, grow and repair/replace

What is a series of events a cell goes through as they grow and divide?

• Cell Division

• Cell Cycle

• Cytokinesis

• Mitosis

Why is DNA important

• it provides the instructions/blueprint for a cell

• it makes energy

• it stores wastes

• it is responsible for making food

What happens during metaphase?

• The DNA gets copied and the cell grows and develops

• Sister Chromatids are lined up along the center of the cell

• The nuclear membrane disappears and the spindle fibers appear

• Two identical daughter cells are formed

What kind of process is DNA replication

• Semi-conservative

• Conservative

• Dispersive

• Complementary

The enzyme used to separate the double helix into 2 single strands is:

• Helicase

• DNA polymerase

• Lipase

• Primase
