Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Chromosomes move to the middle of the spindle during what phase?
A
anaphase
B
telophase
C
metaphase
D
prophase
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. Chromosomes line up at the metaphase plate, under tension from the mitotic spindle. The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.

Detailed explanation-3: -Answer and Explanation: Chromosomes line up on the metaphase plate in the second stage of cell division that is metaphase. During metaphase, chromosomes come together at the equator line because of the mitotic spindle fibers. These fibers emerge from the centrosome present at each pole of the cell.

Detailed explanation-4: -Prophase – The chromosomes shorten and thicken. Metaphase – Chromosomes line up in the middle of the cell. Anaphase – Chromatids break apart at the centromere and move to opposite poles. Telophase – Two nuclei formed after nuclear envelopes reform around each group of chromosomes.

Detailed explanation-5: -During metaphase, chromosomes are organized on an equatorial plate. Metaphase is the stage of eukaryotic cell division when the chromosomes align in the middle of the cell.
