When a cell is in late anaphase of mitosis, which of the following will we see?
A
chromosomes clustered tightly at the center
B
breaking down of the nuclear envelope
C
a clear area in the center of the cell
D
formation of two daughter nuclei
Explanation: 

Detailed explanation-1: -Late anaphase involves both the elongation of overlap microtubules and the use of two distinct sets of motor proteins: one of these pulls overlap microtubules past each other, the other pulls on astral microtubules that have attached to the cell cortex.

Detailed explanation-2: -During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle.

Detailed explanation-3: -Dear Student, Anaphase of Meiosis takes place in the sperm and the ovum cells whereas Anaphase of Mitosis can take place in all cells of the body. In anaphase, the spindle fibres pull homologous chromosomes that are arranged at the equatorial plate, towards opposite poles of the spindle.

Detailed explanation-4: -The unique feature observed in the anaphase is that the chromosomes get divided into sister chromatids that move towards the opposite poles.
