Question:
Each of the peripheral fibrils in centriole are made up of:
Each of the peripheral fibrils in centriole are made up of:
Show Hint
Centrioles always have a 9+0 arrangement of microtubule triplets made of tubulin.
Updated On: Jun 10, 2026
- Tubulin
- Flagellin
- Axonema
- Histone
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Centrioles are cylindrical structures found in animal cells, composed of microtubule triplets.
Step 2: Meaning
Microtubules are proteinaceous filaments that provide structural support to the cell.
Step 3: Analysis
The primary protein component of these microtubules in centrioles is tubulin. Flagellin is the protein in bacterial flagella, and histones are associated with DNA.
Step 4: Conclusion
Tubulin is the fundamental building block of the peripheral fibrils in a centriole.
Final Answer: (A)
