Question

The function of the centrosome is:

• A. Inhibition of cell division
• B. Initiates cell division
• C. To increase protein synthesis
• D. None of the above

Answer 1

The correct option is D

None of the above

The correct option is D.

Explanation of correct option:

1. The centrosphere, also known as kinoplasm, is a particular kind of cytoplasm that contains tiny submicroscopic sub cylindrical structures known as centrioles.
2. They often appear in pairs. Two centrioles that are positioned at a right angle to one another make up the whole complex, which is known as a centrosome.
3. Animal cell cytoplasm is where they may be found.
4. Chromosome movement during cell division is caused by centrosomes, which also give birth to spindle fibers.

Explanation of incorrect options:

Option A:

1. The chromosomes are aligned and dragged via the spindle fibers during cell division.
2. The centrosomes are in charge of producing the spindle fibers and microtubules, both of which are crucial for cell division.
3. Centrosome does not perform the inhibition of cell division.

Option B:

1. A collection of proteins found in centrosomes contribute to the production of microtubules.
2. The proteins control how microtubule formation begins and ends.
3. But it has no role in the initiation of cell division.

Option C:

1. Another name for the centrosomes is the cell's organizing hub for microtubules.
2. They function to control various microtubule and other structural protein movements.
3. But do not contribute in increasing the synthesis of protein.

Final answer: None of the above options (Inhibition of cell division, Initiating cell division, and increasing protein synthesis) are not the function of centrosomes.
