Question

what is the significance of metaphase

Answer 1

The tetrads move to a plane — called the "metaphase plate" — halfway between the two poles of the cell. Next, the spindle fibers attach to the centromeres of each chromosome. ... Note: In metaphase of mitosis, the two kinetochores of each sister chromatid pair attach to spindle 

Answer 2

$\huge\fbox\red{❥answer}$

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. There is an important checkpoint in the middle of mitosis, called the metaphase checkpoint, during which the cell ensures that it is ready to divide.
