Question

How many longitudinal peripheral fibres found in a centriole?

• A. 2
• B. 9
• C. 5
• D. 7

Answer 1

The correct option is B 9

In cell biology, a centriole is a cylindrical cell structure composed mainly of a protein called tubulin that is found in most eukaryotic cells. It is made from nine triplets of microtubules formed into a cylinder. The pattern of the microtubules for a ring of 9 microtubules known as "triplets" and the microtubules are arranged at right angles to one another. Each of the centriole is made up of nine triplet peripheral fibers and these triplet fibers are arranged in a circular manner that gives it a barrel-shaped appearance. Within the centrosome a mother centriole and the daughter centriole are arranged at perpendicular angles to each other. These two centrioles are tightly attached to each other and are surrounded by dense matrix called pericentriolar material.
