Mitosis and Heredity Review
1. As you become an adult, the cells in you body
A. keep dividingB. stop dividingC. grow biggerD. can’t repair themselves
A
A. Their chromatids join.B. They go through telophase.C. They divide.D. They become specialized.
C
2. How do cells share genetic material?
3. The cell cycle begins with
A. cytokinesisB. interphaseC. mitosisD. metaphase
B
A
4. The cell cycle ends with
A. cytokenesisB. InterphaseC. metaphaseD. prophase
5. How does a cell prepare for mitosis?
A. It goes through cytoKinesis.B. It forms new chromosomes.C. It rests during interphase.D. It makes exact copies of its DNA.
D
6. A cell grows and carries out life functions in
A. telephaseB. prophaseC. anaphaseD. interphase
D
7. What process completes division in a plant cell?
A. A cell plate grows between the two new nuclei.
B. A fiber ring forms in the center of the dividing cell.
C. The cell membrane is pinched inward.D. Chromosomes line up in the middle of the
cell.
A
8. Bread yeast reproduce by developing tiny extensions on their bodies. This is an
example of
A. buddingB. binary fissionC. regenerationD. sexual reproduction
A
9. The offspring produce by asexual reproduction
A. are genetically identical to their parentsB. are genetically different from their
parentsC. have half as much DNA as their parentsD. get half of their DNA from each parent
A
10. Many offspring can be produced very quickly
A. during a single cell cycleB. through the formation of
chromosomesC. when two parent cells produce one
offspringD. through asexual reproduction
D
11. Which of the following is true of all cells?
A. All cells have DNA in their nucleusB. All cells come from existing cells.C. All cells are specialized.D. All cells reproduce by budding
B
12. A cell produces two genetically identical daughter cells when it
A. condenses DNAB. make proteinsC. undergoes mitosisD. enters interphase
C
13. Most multicellular organisms grow and develop because their cells
A. grow smaller with ageB. become specialized at birthC. divide during interphaseD. continue to divide
D
14. Which of the following correctly sequences the steps in the cell cycle?
A. cytokinesis, mitosis, interphaseB. telophase, anaphase, metaphase,
prophaseC. interphase, mitosis, cytokinesisD. prophase, anaphase, metaphase,
telophase C
15. Cells prepare for cell division during
A. interphase by duplicating their DNAB. mitosis by dividing their DNAC. Anaphase by condensing their DNAD. telophase by splitting their DNA
A
16. What happens during mitosis
A. chromosomes line up in the center of the cell.
B. Cytokinesis takes place.C. A cell completes one entire cell
cycle.D. The cell nucleus makes two copies
of DNA
A
17. After mitosis, the number of chromosomes in a daughter cell is
A. half the number in the parent cellB. one-quater the number in the
parent cellC. twice the number in the parent cellD. the same as the number in the
parent cell
D
18. Asexual reproduction in most organisms involves
A. mitosis by two parentsB. mitosis by one parentC. binary fission by both parentsD. regeneration by one parent
B
19. Your genes are inherited from your
A. parentsB. allellesC. gametesD. offspring
A
20. Various forms of the same gene are called
A. chromosomesB. allelesC. homologsD. genotypes
B
A. dominantB. incompleteC. not hereditaryD. recessive
21. An animal has an allele for white fur, but its fur is black. The allele for
white fur is
D
22. Your eye color is a(n)
A. alleleB. homologC. phenotypeD. genotype
C
23. The way in which parents’ alleles might combine in their offspring can be
shown in a
A. phenotypeB. genotypeC. coin tossD. Punnett square
D
24. In a plant, tall (D) is the dominant allele. Short (d) is the recessive allele. Which genotype
would a short offspring have?
A. dDB. ddC. DdD. DD
B
25. DNA is always copied before the process of cell division called
