    5. Enone of the above
  2. 2If two chromosomes are homologous, they
    1. Alook similar under the microscope
    2. Bhave very similar DNA sequences
    3. Ccarry the same types of genes
    4. Dmay carry different versions of the same gene
    5. Eare all of the above
  3. 3Checkpoints during the cell cycle are important because they
    1. Aallow the organelle activity to catch up to cellular demands
    2. Bensure the integrity of the cell's DNA
    3. Callow the cell to generate sufficient ATP for cellular division
    4. Dare the only time DNA replication can occur
    5. Edo all of the above
  4. 4Which of the following is a reason for mitotic cell division?
    1. Aasexual reproduction
    2. Bgamete formation in animals
    3. Cmulticellularity
    4. Dall of the above
    5. Eboth a and c
  5. 5A replicated chromosome is composed of
    1. Atwo homologous chromosomes held together at the centromere.
    2. Bfour sister chromatids held together at the centromere.
    3. Ctwo sister chromatids held together at the centromere
    4. Dfour homologous chromosomes held together at the centromere.
    5. Eone chromosome with a centromere.
  6. 6Which of the following is not an event of anaphase of mitosis?
    1. AThe nuclear envelope breaks apart
    2. BSister chromatids separate
    3. CKinetochore microtubules shorten, pulling the chromosomes to the poles.
    4. DPolar microtubules push against each other, moving the poles father apart.
    5. EAll of the above occur during anaphase.
  7. 7A student is looking at cells under the microscope. The cells are from an organism that has a diploid number of 14. In one particular case, the cell has seven replicated chromosomes (sister chromatids) aligned at the metaphase plate of the cell. Which of the following statements accurately describes the particular cell?
    1. AThe cell is in metaphase of mitosis.
    2. BThe cell is in metaphase of meiosis I.
    3. CThe cell is in metaphase of meiosis II.

    5. EBoth b and c are correct.
  8. 8Which of the following statements accurately describes a difference between mitosis and meiosis?
    1. AMitosis may produce diploid cells, where as meiosis produces haploid cells.
    2. BHomologous chromosomes synapse during meiosis but do not synapse during mitosis.
    3. CCrossing over commonly occurs during meiosis, but it does not commonly occur during mitosis.
    4. DAll of the above are correct
    5. EBoth a and c are correct.
  9. 9During crossing over in meiosis I,
    1. Ahomologous chromosomes are not altered.
    2. Bhomologous chromosomes exchange genetic material.

    4. Dgenetic information is lost
    5. Ecytokinesis occurs
  10. 10Aneuploidy may be the result of
    1. ADuplication of a region of a chromosome
    2. BInversion of a region of a chromosome
    3. Cnondisjunction during meiosis
