Question

laboratory 1 | cytology and early development

1. use textbook focus figure 3.4 (pages100 & 101), lab manual figure 1.7, the mitosis charts and mitosis models to determine in which phases cytokinesis begins and ends.

○ cytokinesis begins
○ cytokinesis ends

Explanation:

Step1: Recall cell - division knowledge

Cytokinesis is the division of the cytoplasm. In mitosis, it begins towards the end of anaphase when the sister chromatids have separated and are moving towards the poles.

Step2: Determine the end - phase

Cytokinesis ends at the end of telophase when two distinct daughter cells have been formed with their own nuclei and cytoplasm.

Answer:

Cytokinesis begins: Anaphase
Cytokinesis ends: Telophase
