Which processes depend on microtubules?
Hints
- Three are microtubule jobs; one belongs to actin.
- The contractile ring that divides the cytoplasm is made of actin and myosin.
Show the answer
- A. Beating of cilia and flagella
- B. Separation of chromosomes in mitosis
- D. Movement of vesicles through the cytoplasm
Why
Microtubules handle transport, ciliary beating and chromosome separation. Cytokinesis is actin’s job, a contractile ring of actin and myosin pinches the cell, which is why the two systems are needed in sequence.
