Question

Which statement correctly describes the structure of a centriole? A) 3 groups of 9 microtubules B) 4 groups of 6 microtubules C) 6 groups of 4 microtubules D) 9 groups of 3 microtubules

Answer 1

The right answer is D) 9 groups of 3 microtubules

Centrioles are the constituents of a so-called centrosome structure: every animal cell has a centrosome, which is made of two centrioles and which together form a functional unit. A centriole consists of nine triplets inclined microtubules, surrounded by a number of proteins.
