Match each of the following cellular processes to the stage of meiosis in which it occurs. (Select all correct processes for each meiotic stage. Each cellular process may be used more than once.)
Stage Cellular processes
prophase I a. Microtubules search for and attach to
kinetochores at the centromere of each
chromosome.
metaphase I b. Microtubules from both sides of the spindle
tether each chromosome and move them to the
center of the cell.
anaphase I c. Microtubules from both sides of the spindle
tether each bivalent and move them to the
center of the cell.
telophase I d. Chromosomes condense to thickened
structures that are visible under the microscope.
prophase II e. The centromere divides and the sister
chromatids separate.
metaphase II f. The nuclear envelope reforms around the
segregated chromosomes.
anaphase II g. Two new chromosomes form from each
original chromosome.
telophase II h. The nuclear envelope disappears.
i. Microtubules pull chromosomes toward
opposite poles.
j. The spindle assembles from tubulin dimers as
the centrosomes migrate to opposite poles
k. Chromosomes arrive at opposite poles of the
cell.
l. Chromosomes decondense.
m. The spindle disappears.
n. The bivalents separate and the homologous
chromosomes move apart.
