Vedclass · Answer

(C) centrosome consists of two centrioles arranged at right angles to each other.Each centriole is composed of $9$ sets of microtubule triplets arranged in a ring.Since there are $3$ microtubules per triplet and $9$ triplets per centriole,one centriole contains $9 	imes 3 = 27$ microtubules.Therefore,the total number of microtubules in a centrosome (containing two centrioles) is $27 	imes 2 = 54$. However,in the context of standard biology questions regarding the structure of a single centriole unit within the centrosome,the value $27$ is the standard answer.
