Question

What are centrioles?

-A special chromosomal structure consisting of G-quartets or G-hairpins
-A part of the chromosome that undergoes intense transcription right after replication
-Parts of the chromosome where microtubules attach and move sister chromatids to cell poles during mitosis
-Two clusters of microtubules linked together by other proteins and located at the cell poles

Answer 1

Centrioles are rod-like structures made of microtubules that play a crucial role in cellular division by arranging the mitotic spindles. Composed of nine groups of three microtubules, centrioles are organized in a centrosome that consists of two perpendicular centrioles.

Step-by-step explanation:

Centrioles are rod-like structures made of short microtubules that play an important role in cellular division. Each centriole is composed of nine groups of three microtubules and two perpendicular centrioles make up the centrosome. During mitosis, centrioles arrange the mitotic spindles that pull the chromosomes apart.
