Chromosomes uncoil
A
Prophase
B
Metaphase
C
Anaphase
D
Telophase
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -During telophase, the chromosomes begin to uncoil and form chromatin. This prepares the genetic material for directing the metabolic activities of the new cells. The spindle also breaks down, and new nuclear membranes form.

Detailed explanation-3: -Finally, during telophase II, the sister chromosomes uncoil, new nuclear membranes form, and the two cells are divided again, forming four new haploid cells called gametes.

Detailed explanation-4: -During telophase, chromosomes arrive at opposite poles and unwind (uncoil) into thin strands of DNA, the spindle fibers disappear, and the nuclear membrane reappears.

Detailed explanation-5: -Chromosomes begin to uncoil during anaphase. During metaphase, sister chromatids line up along the equator of the cell. After mitosis, the result is typically two daughter cells with identical DNA to each other.
