Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
At this point in time, replicated chromosomes (not paired) are aligned in the center of the cell:
A
Prophase II
B
Prometaphase II
C
Metaphase II
D
Anaphase II
Explanation: 

Detailed explanation-1: -Metaphase: During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate.

Detailed explanation-2: -During metaphase II, the centromeres of the paired chromatids align along the equatorial plate in both cells. Then in anaphase II, the chromosomes separate at the centromeres. The spindle fibers pull the separated chromosomes toward each pole of the cell.

Detailed explanation-3: -Answer and Explanation: The above statement, “Homologous pairs of chromosomes line up at the metaphase plate during metaphase II” is a true statement.

Detailed explanation-4: -During metaphase, the nucleus dissolves and the cell’s chromosomes condense and move together, aligning in the center of the dividing cell. At this stage, the chromosomes are distinguishable when viewed through a microscope.
