What drives the separation of centrosomes?
A)motor proteins associated with microfilaments
B)motor proteins associated with adjacent microtubules
C)contraction of individual microfilaments
D)sliding of adjacent microfilaments over one another
E)contraction of adjacent microtubules

Question

Quizplus · Accepted Answer

Motor proteins associated with adjacent microtubules pull the centrosomes apart during cell division. This process is driven by the activity of dynein and kinesin motor proteins. Motor proteins associated with microfilaments (choice A) are not involved in centrosome separation. Contraction of individual microfilaments (choice C) and sliding of adjacent microfilaments over one another (choice D) are both processes associated with muscle contraction, but not with centrosome separation. Contraction of adjacent microtubules (choice E) is not a recognized biological process.
