Question

Cell organelle having a cartwheel constitution is ____________.

• A. Centriole and basal body
• B. Microtubule
• C. Microfilament
• D. Basal plate

Answer 1

The correct option is A Centriole and basal body

A. Centriole and basal body

Reason: The cartwheel is a sub-centriolar structure which consists of a central hub and nine radially arranged spokes, located at the proximal end of the centriole. It appears at the initial stage of the centriole assembly process as the first nine fold symmetrical structure. Also, a 9+0 microtubule constitution with cartwheel structure is present in the proximal region of the basal body, which is present in the base of the flagella or cilia.

So the correct option is A.
