Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Microtubules ____ during telophase
A
Break down
B
Build up from centrosomes
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The spindle continues to elongate during telophase, as the chromosomes arriving at the poles are released from the spindle microtubules and the nuclear envelope re-forms around them. Both the assembly and the function of the mitotic spindle depend on microtubule-dependent motor proteins.

Detailed explanation-2: -Telophase begins when the decondensing daughter chromatids arrive at the poles, the kinetochore microtubules disappear, and the nuclear envelope reforms around the decondensing chromosomes to form the two daughter nuclei (Benavente, 1991).

Detailed explanation-3: -During telophase, a nuclear membrane forms around each set of chromosomes to separate the nuclear DNA from the cytoplasm. The chromosomes begin to uncoil, which makes them diffuse and less compact.
