Although the process of chromosome partitioning during mitosis is visible through a light microscope, the process of dna replication is not. why?

Because chromosomes are highly condensed during mitosis

Explanation:

Chromosomes are structures of packed and organized DNA molecules together with proteins. They are only visible under a light microscope only when the cell is undergoing the metaphase of cell division ( aligned in the center-metaphase plate). In this phase chromosomes are in their condensed form and easiest to distinguish and study.

DNA replication occurs during the S phase of interphase, which is the phase before cell division.

it's not c. i took the quiz and got it wrong. so my best guess is b.

have a great day, and hope this .

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
