Question

Mitosis unfolds through a sequence of stages marked by specific events in the cell. The structural changes in the cell are brought about by a series of tightly coordinated underlying mechanisms.
Sort each process into the appropriate bin to indicate the stage of mitosis in which it occurs. If a process occurs in more than one stage, sort it to the stage when it first occurs.
1. Cohesins join sister chromatids of duplicated chromosome.
2.Tubulins assemble into spindle microtubules.
3. Microtubules attach to kinetochores.
4. Spindle microtubules disassemble.
5. Kinetochores are motionless in relation to poles of cell.
6. Kinetochores move toward poles of cell.
7. Cohesins break down.
a. Prophase
b. prometaphase
c. metaphase
d. anaphase
e. telophase

Answer 1

Answer:

1.- Prophase:  

Cohesins join sister chromatids of duplicated chromosome.

2.- Prometaphase:

Microtubules attach to kinetochores.

3.- Metaphase:

Kinetochores are motionless in relation to poles of cell.

4.- Anaphase:

Kinetochores move toward poles of cell

5.- Telophase:

Spindle micrutubules disassemble.
