Question
For the following events below, indicate what part of the cell cycle it occurs in (interphase, prophase, metaphase, anaphase, telophase, cytokinesis). Some answers may be used more than once.
a) The nucleolus begins to disintegrate.
b) Chromatids separate at the beginning of this phase.
c) The chromasomes move towards the center of the cell.
d) A chromatid from each pair is now attached at each pole.
e) The cell grows rapidly.
f) Separate spindle fibers become attached to the centromeres of each chromosome.
g) Separate chromosomes are not clearly visible but the chromatin has become thicker and shorter.
h) A cell plate completely divides a plant cell.
Explanation / Answer
a) The nucleolus begins to disintegrate in prophase.
b) Chromatids separate at the beginning of anaphase.
c) The chromosomes move towards the center of the cell during metaphase.
d) A chromatid from each pair is now attached at each pole by the end of telophase.
e) The cell grows rapidly in G1 stage of interphase.
f) Separate spindle fibers become attached to the centromeres of each chromosome during metaphase.
g) Separate chromosomes are not clearly visible but the chromatin has become thicker and shorter in prophase.
h) A cell plate completely divides a plant cell during cytokinesis.
