How might spindle microtubules assist in the process of splitting centromeres?
A)the use of motor proteins to split the centromere at specific arginine residues
B)creating tension by pulling toward opposite poles
C)coding for enzymes involved in the process
D)phosphorylating the centromere,which changes its conformation

Question

Quizplus · Accepted Answer

Spindle microtubules create tension by pulling the sister chromatids toward opposite poles, which helps to split the centromeres. This tension is created by the attachment of the microtubules to the kinetochores on the sister chromatids. The use of motor proteins and coding for enzymes may also play a role in the process, but the main mechanism by which spindle microtubules assist in splitting centromeres is through the creation of tension. Phosphorylation may play a role in regulating the process, but it is not directly involved in splitting the centromeres.
