Question

D Question 15 4 pts Select all of the following statements that apply to prophase and prometaphase: Hint: • Mitosis Phases video Textbook chapter 10 section 10.2 Chromosomes become visible. The nuclear envelope forms around the chromosomes Centrosomes separate and migrate towards opposite sides of the cell Polar microtubules (aka non-kinetochorespindles lengthen. The chromosomes become tightly coiled with condensin proteins The microtubules become attached to the kinetochores. i Cohesin proteins become degraded.

Answer 1

After interphase comes prophase then metaphase then anaphase and last telophase followed by cytokinesis.

The phase between end of prophase or late prophase and just before starting of metaphase of early metaphase is known as prometaphase.

So, according to the questions the correct statements are.

a) Chromosome becomes visible

b) Centrosomes separated and migrates towards opposite sides of the cell.

c) The chromosomes becomes tightly colled with condensin protein.

d) The microtubules becomes attached to the kinetochores.

Only this four statement is correct regarding prophase and prometaphase.

Explanation for wrong statements.

Cohesin protein becomes degraded during Anaphase.

Polar microtubules becomes lengthen during Anaphase.

The nuclear envelope forms around the chromosomes during Telophase.
