Question

1. what holds the chromatids together?
2. when do the sister chromatids separate?
3. during which phase do chromosomes first become visible?
4. during which phase does the cleavage furrow start forming?
5. what is another name for mitosis?
6. complete the following table by checking the correct column for each statement.

Explanation:

• For question 6: In animal cell cytokinesis, the cleavage furrow starts forming during telophase. It is a contractile ring - composed of actin and myosin - that pinches the cell to divide the cytoplasm.
• For question 7: Mitosis is also known as equational division. This is because the daughter cells formed have the same number of chromosomes as the parent cell (in somatic cells), maintaining the chromosome number (equational).

Answer:

1. Telophase
2. Equational division
