Spindles are ___

Question

Spindles are ___.  
A) permanent cell structures
B) present throughout every step of mitosis
C) present during interphase
D) mainly composed of microtubules
E) all identical

Accepted Answer

Spindles are mainly composed of microtubules. While spindles are present throughout every step of mitosis, they are not permanent cell structures as they break down after cell division is complete. Spindles are not present during interphase, as they only form during cell division. Additionally, spindles may not be all identical as they may have variations in their composition and organization.
