What happen during metaphase stage of mitosis?

Answer 1

In metaphase, the chromosomes line up in the center of the cell (aka the metaphase plate or equatorial plate) and then the spindle fibers attach to the centromeres.

Centromeres: the center of the two conjoined chromosome pairs where they will break into two halves in the next phase

Answer 2

during this the spindle fully develops and the chromosomes align at the metaphase plate.

the changes that occur during this is the nuclear membrane disappears completely, in animal cells, the 2 pairs of centrioles align at the opposite poles at the cell, polar fibers continue to extend from the poles to the center of the cell, chromosomes move reandomly until they attatch to polar fibers from both sides of their centromeres, chromosomes align at the metaphase plate at right angles to the spindle poles, and chromosomes are held at the metaphase plate by equal forces of the polar fibers pushing on the centromeres of the chromosomes.

Answer 3

It is when the chromosomes align along the equilateral plane of the cell.

Answer 4

It is where condensed and highly coiled chromosomes align in the middle of the cell before being separated into the two daughter cells.

Answer 5

the tetrads line up randomly along the

midline of the cell, and spindle fibers attach to the

centromere of each homologue.

Answer 6

in mytosis in the cell cycle, during metaphase, the chromosomes line up on the equator/at the center of the cell before being split apart in anaphase.

Answer 7

The cell begins to spit into two cells.
