The mitotic cell cycle is divided into a number of stages. In which of the following stages will the chromosomes line up at the equator of the cell?
|
|
Anaphase
|
|
|
Interphase
|
|
|
Metaphase
|
|
|
Telophase
|
Explanation:
Detailed explanation-1: -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-2: -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-3: -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.
