Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following describes the location of the chromosomes during metaphase?
A
located in the nucleus of the cell
B
scattered throughout the cytoplasm
C
clustered at each pole of the cell
D
lined up along the equator of the cell
Explanation: 

Detailed explanation-1: -During metaphase, the kinetochore microtubules pull the sister chromatids back and forth until they align along the equator of the cell, called the equatorial plane.

Detailed explanation-2: -Metaphase Normally, individual chromosomes are spread out in the cell nucleus. 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.

Detailed explanation-3: -During metaphase, the microtubules pull the sister chromatids back and forth until they align in a plane, called the equatorial plane, along the center of the cell. During anaphase, the sister chromatids are separated simultaneously at their centromeres.

Detailed explanation-4: -During mitosis, chromosomes are bound to microtubules emanating from both poles of the mitotic spindle via sister-kinetochores and aligned on the metaphase plate precisely in the middle of the spindle.

Detailed explanation-5: -metaphase – chromosomes line up at the middle of the cell, along the plane of cell division, pushed and pulled by microtubules of the spindle apparatus. anaphase – sister chromatids separate and migrate towards opposite ends of the cell.
