Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In anaphase of mitosis, chromosomes
A
form and the nuclear envelope disappears.
B
are pulled toward opposite ends of the cell.
C
chromosomes line up along the equator of the cell
D
chromosomes begin to decondense and the two new nuclei begin to form.
Explanation: 

Detailed explanation-1: -The separated chromosomes are then pulled by the spindle to opposite poles of the cell. Anaphase ensures that each daughter cell receives an identical set of chromosomes, and it is followed by the fifth and final phase of mitosis, known as telophase .

Detailed explanation-2: -Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.

Detailed explanation-3: -The segregation of the replicated chromosomes is brought about by a complex cytoskeletal machine with many moving parts-the mitotic spindle. It is constructed from microtubules and their associated proteins, which both pull the daughter chromosomes toward the poles of the spindle and move the poles apart.
