Q:

When during the Cell Cycle are Chromosomes visible?

A) only during interphase B) only during cell division
C) only during G1 phase D) only during they are replicated
 
Answer & Explanation Answer: B) only during cell division

Explanation:

During most of the cell cycle, interphase, the chromosomes are somewhat less condensed and are not visible as individual objects under the light microscope. However during cell division, mitosis, the chromosomes become highly condensed and are then visible as dark distinct bodies within the nuclei of cells. The chromosomes are most easily seen and identified at the metaphase stage of cell division and most of the chromosome images in this gallery are pictures of metaphase chromomosomes.

The cell division takes place in mitosis stage.
