Structure of centrosome


Centrosome is a small naked organelle found in the cytoplasm of animal cell near the outer surface of the nucleus. It consists of two bundles of microtubules called centrioles that lie at right-angles to each other. Centrioles are short cylinders and possess a whorl of 9 peripheral fibrils. The fibrils are absent in the centre. Each fibrils are made of 3 sub-fibres. There is a proteinaceous hub in the central part of a centriole.


Direction : In the following questions the Assertions (A) and Reasons (R) have been put forward. Read both the statements and choose the correct option from the following:


Assertion : Centrioles are the self-duplicating bodies. They contain DNA and RNA.


Reason : The centrioles are converted into basal bodies which give rise to cilia and flagella.

  • a)
    A is true but R is false. 

  • b)
    Both A and R are true, but R is not the correct explanation of A.

  • c)
    Both A and R are true, and R is the correct explanation of A.

  • d)
    A is false but R is true.

Correct answer is option 'A'. Can you explain this answer?
Verified Answer
Structure of centrosomeCentrosome is a small naked organelle found in ...
Centrioles are self-duplicating bodies that play a role in cell division and the organization of microtubules. However, they do not contain DNA and RNA. Centrioles are not directly converted into basal bodies; rather, basal bodies are derived from centrioles and are involved in the formation of cilia and flagella. Therefore, the reason provided in statement R is not correct.
Hence, option 3 is the correct choice: A is true, but R is false.

Assertion and Reasoning:

Assertion: Centrioles are the self-duplicating bodies. They contain DNA and RNA.

Reasoning: The centrioles are converted into basal bodies which give rise to cilia and flagella.

Explanation:

Centrioles are small, cylindrical structures found in eukaryotic cells. They are composed of microtubules and are involved in various cellular processes such as cell division, organization of microtubules, and formation of cilia and flagella. The given assertion is true as centrioles are self-duplicating bodies that contain DNA and RNA. However, the reasoning is not entirely correct. While it is true that centrioles can be converted into basal bodies, which in turn give rise to cilia and flagella, it is not the only function of centrioles.

Functions of Centrioles:

1. Formation of spindle fibers during cell division.

2. Organization of microtubules in the cytoskeleton.

3. Formation of cilia and flagella.

4. Maintenance of cell shape and polarity.

Conclusion:

Both the assertion and reasoning are true, but the reasoning is not the correct explanation of the assertion. The centrioles are self-duplicating bodies that contain DNA and RNA and are involved in various cellular processes. While centrioles can be converted into basal bodies, it is not the only function of centrioles.
