Final answer:
Centrioles organize microtubules and assist in cell division, but they are not involved in RNA synthesis or lipid synthesis.
Step-by-step explanation:
The structural and functional characteristics of centrioles include their role in organizing microtubules and their involvement in cell division. Centrioles are composed of nine triplets of microtubules arrayed in a cylinder and are positioned at right angles to each other within the centrosome, which is the microtubule-organizing center.
These structures are crucial during cell division, where they help organize the mitotic spindle that segregates chromosomes into two new cells. However, centrioles are not involved in the synthesis of RNA or lipids.
To answer the specific question: the structural and functional characteristics of centrioles that apply are B) Organization of microtubules and C) Cell division. They do not contribute to A) Synthesis of RNA or D) Lipid synthesis.
