When during the cell cycle do chromosomes first become visible?

a.) during interphase
b.) during cytokinesis
c.) during prophase
d.) during the g1 phase

Answer;

C.) during prophase

Explanation;

-Prophase is the first phase of mitosis, the process of cell division in which a parent cell divides into two daughter cells that are similar to the parent cell, and is separated into four stages.

-During this phase of mitosis each chromosome becomes condensed and more visible, and there is the breakdown of the nuclear membrane and appearance of spindle fibers.

-Initially, prior to prophase, the chromosomes were long strands of DNA material called 'chromatin', which then curls up into tightly wound shapes called chromosomes.
