MITOSIS AND MEIOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Telophase is the stage where the nuclear membrane reforms and chromosomes uncoil ____
A
True
B
False
Explanation: 

Detailed explanation-1: -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-2: -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-3: -Telophase starts when the replicated, paired chromosomes are divided and pushed to opposite sides, or poles, of the cell. Complete answer: A nuclear membrane forms around each set of chromosomes during the telophase to separate the nuclear DNA from the cytoplasm.

Detailed explanation-4: -Telophase. The final stage of mitosis, and a reversal of many of the processes observed during prophase. The nuclear membrane reforms around the chromosomes grouped at either pole of the cell, the chromosomes uncoil and become diffuse, and the spindle fibres disappear.

Detailed explanation-5: -In addition, the cytoplasmic network of microtubules begins to once again define the cellular structure. The nuclear membrane is reassembled during late telophase from vesicles that surround individual chromosomes, which eventually fuse into larger groups that finally associate to complete the structure.
