Question

The mitotic spindles arise from which cell structure?

a. centromere

b. centrosome

c. kinetochore

d. cleavage furrow

Short answer

The correct option is B.

Step-by-step solution

Step. 1 Introduction 

The mitotic spindle fiber seems to be a structure that arises following cell division and thus is responsible for separating identical chromosomes.

Step. 2 Explanation for correct option. 

Mitotic spindles are structures created throughout the cell cycle that divide copy chromosomes in the cells. They are produced by the centrosome.

Step. 3 Explanation for incorrect option. 

Option a. Centromeres are genomic sites that regulate kinetochore formation and spindle interaction throughout cell division.

Option c. A kinetochore seems to be a protein area present upon every chromatid's centromere.

Option d. The cleavage furrow seems to be the depression on the surface of the cell that initiates the cleavage process.
