Which of the following statements about mitosis is incorrect?
a. Microtubules from the spindle poles attach to the kinetochores on the chromosomes.
b. In anaphase, the spindle separates sister chromatids and pulls them apart.
c. In metaphase, spindle microtubules align the chromosomes at the spindle midpoint.
d. Cytokinesis describes the movement of chromosomes.
e. Both the animal cell furrow and the plant cell plate form at their former spindle midpoint.
Match the following events with the stages in mitosis:
chromosomal materials condenses to form compact chromosomes.
alignment of chromosomes along the equator or plate with microtubules attached to poles
sister chromatids for each chromosome split and move to opposite poles
chromosomes are clustered at each of the poles and give way to cytokinesis
A.
telophase
B.
anaphase
C.
metaphase
D.
prophase
With regard to the process of mitosis, which of the following pairs is NOT matched correctly?
a. Interphase - the cell grows, chromosomes replicate, and proteins are produced to prepare the
cell to divide
Ob. Prophase - chromosomes condense, and the nuclear membrane dissociates/breaks down
c. Metaphase - chromosomes move toward opposite poles (or sides) of the cell
d. Anaphase - sister chromatids separate
e. Telophase - two distinct nuclei are formed; this is the stage immediately before cytokinesis
