Replication of DNA occurs at the interphase stage of the cycle.

The DNA contains the genetic makeup of the cell. It must be copied exactly to maintain similarity and therefore the resulting cells are identical copies of their parent cell.

Chromosomes become visible during mitosis because they condense themselves to thick, visible strands. Regularly, they are more spread out as thin strands and therefore invisible to the eye even with a microscope.

The blue region appears to be the lined up thick chromosomes in metaphase. They are visible because of their thickness and their alignment.

b) prophase

c) anaphase

d) telophase

e) anaphase

f) interphase stages S, G1, and G2

a) telophase

During the cell cycle a cell grows, replicates DNA, the DNA aligns at the middle of the cell and begins to split towards opposite sides until the cell cleaves into two daughter cells.

The word resting suggests that the cell is resting and it implies that it is not carrying out any function. This is incorrect because even in the interphase, the cell is performing all its regular functions like respiration, excretion and other specialized functions and “not resting”.
