Question

The base body of cilia or flagella are structurally equivalent to _____________.

• A. Centriole
• B. Kinetochore
• C. Centromere
• D. Nuclear matrix

Answer 1

The correct option is A Centriole

A basal body is a protein structure found at the base of a eukaryotic undulipodium. Undulipodium or a 9+2 organelle is a motile filamentous extracellular projection of eukaryotic cells. It is basically synonymous to flagella and cilia which are differing terms for similar molecular structures used on different types of cells.

Basal body is formed from a centriole and several additional protein structures, and is essentially a modified centriole. The basal body serves as a nucleation site for the growth of the axoneme microtubules.

Hence, the correct answer is 'Centriole'.
