Question

Cytokinesis involves all of the following EXCEPT:

a. formation of a cleavage furrow
b. formation of a contractile ring
c. assembly of a basal body
d. assembly of an actinomyosin complex
positional information from the spindle
e. specifying the cleavage plane

Answer 1

Cytokinesis involves the formation of a cleavage furrow, a contractile ring composed of actin filaments, and specifying the cleavage plane. It does not involve the assembly of a basal body or an actinomyosin complex.

Step-by-step explanation:

Cytokinesis involves several processes that result in the division of the cytoplasm and the formation of two daughter cells. These processes include the formation of a cleavage furrow, the formation of a contractile ring composed of actin filaments, and specifying the cleavage plane. However, cytokinesis does not involve the assembly of a basal body, which is responsible for the formation of cilia and flagella, or the assembly of an actinomyosin complex, which is involved in muscle contraction.
