Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During which phase of mitosis do chomosome pairs line up along the equator of the cell?
A
Anaphase
B
Cytokinesis
C
Metaphase
D
Interphase
Explanation: 

Detailed explanation-1: -Chromosomes, consisting of sister chromatids, line up at the equator or middle of the cell during metaphase.

Detailed explanation-2: -Metaphase: During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate. Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate.

Detailed explanation-3: -The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase II, the chromosomes line up individually along the metaphase plate. In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell.

Detailed explanation-4: -During metaphase II, the chromosomes align along the cell’s equatorial plate. During metaphase II, the chromosomes align along the cell’s equatorial plate.
