Mitosis Online Practice Answers (Unit 7 Lesson 10: Mitosis Apply)
1. What is the purpose of mitosis
□ Cell specialization
□ Uncontrolled cellular growth
■ Production of new cells
□ Production of sperm and ova
2. In which phase of mitosis does DNA condense into chromosomes?
□ Interphase
□ Telophase
□ Metaphase
■ Prophase
3. Mitosis is the only type of cellular division in which
□ DNA is replicated
■ One parent cell duplicates itself into two identical daughter cells
□ One parent cell duplicates itself into four daughter cells
□ The genetic material differs between the parent and daughter cells
4. An epithelial cell replicates 16 times before entering a state of quiescence. These replicate daughter cells are
□ Further differentiated into specialized cells.
□ Replicated indefinitely.
■ Genetically the same as the parent cell.
□ Phenotypically the same as the parent cell.
5. In which phase of mitosis are the chromosomes separated and pulled to opposite sides of the cell?
□ Prophase
■ Anaphase
□ Telophase
□ Metaphase
6. Two new nuclei are formed during which phase of mitosis?
□ Anaphase
□ Prophase
□ Metaphase
■ Telophase
7. Mitosis is a part of the cell cycle that occurs in all of the following except
□ Protozoans
□ Zooplankton
■ Amoebas
□ Bacteria
8. Consider the process of gene expression. Select the answer that places the steps of gene expression in the correct order.
□ RNA spliced → DNA transcribed → mRNA translated → ribosomes make proteins
□ DNA transcribed → mRNA translated → RNA spliced → ribosomes make proteins
■ DNA transcribed → RNA spliced → mRNA translated → ribosomes make proteins
□ mRNA translated → RNA spliced → DNA transcribed → ribosomes make proteins
9. Which process is being shown in this image?
□ Cell differentiation
□ Senescence
□ Mitosis
■ Gene expression
10. An increase in cell population is called
■ Proliferation
□ Cell differentiation
□ Fibroblast
□ Apoptosis
11. Which cells are responsible for blood clotting?
□ Fibroblasts
□ Basal cells
■ Platelets
□ Macrophages
12. Which statement explains a potential benefit of being a naturally polyploid organism, such as a banana or an amphibian?
■ Natural polyploidy may protect a cell from harmful mutations.
□ Natural polyploidy may increase an organism’s size.
□ Natural polyploidy may decrease the rate of mitosis in cells.
□ Natural polyploidy may protect a cell from gene duplicity.
13. Benzene, a by-product found in cigarettes, increases the risks of cancer and
□ Chronic bronchitis
□ Susceptibility to infections
■ Miscarriage
□ High blood pressure
