Question

Do centrioles have DNA?

Answer 1

Centrioles:

1. A centriole is composed of nine (9) sets of triplet microtubules.
2. A triplet consists of one complete microtubule joined by two incomplete microtubules.
3. Two centrioles are arranged such that one is perpendicular to the other.
4. A centriole is a small cylinder-like structure or a hollow cylinder.
5. Centrioles organize a 'cloud' of protein material around them, this dense material called the pericentriolar matrix (PCM), both of which form the all-important centrosomes.
6. Centrioles contain RNA, which participates in the formation of esters during mitosis.
7. In animal cells, centrioles form spindle fibers during cell division.

Final Answer: No, centrioles do not contain DNA.
