Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which phase of mitosis is where the chromosomes line up in the middle of the cell?
A
Prophase
B
Metaphase
C
Anaphase
D
Telophase
Explanation: 

Detailed explanation-1: -During metaphase, the cell’s chromosomes align themselves in the middle of the cell through a type of cellular “tug of war.” The chromosomes, which have been replicated and remain joined at a central point called the centromere, are called sister chromatids.

Detailed explanation-2: -Metaphase (the shortest phase of mitosis) is characterized by two events: Chromosomes line up across the middle of the cell. Spindle fibers connect the centromere of each sister chromatid to the poles of the cell.

Detailed explanation-3: -Spindle fibers align the chromosomes along the middle of the cell nucleus. This line is referred to as the metaphase plate.
