When the cell is dividing itself.
NO light microscope can not magnify the image to see chromosomes. You can see with fluorescence microscopes to observe them during cell cycle. Light microscope is helpful to check the whole living cell.
During Interphase the DNA is not in the form of chromosomes. It is not until Prophase that it condenses and chromosomes become visible.
DNA in the form of chromosomes and sister chromatids (which are identical replicated chromosomes).
Chromosomes become visible during cell division because they condense and coil up, which makes them more compact and easier to separate into daughter cells. This condensed form helps ensure equal distribution of genetic material to the new cells.
Chromosomes are not always visible because they are usually tightly packed and condensed into a structure called chromatin during most phases of the cell cycle. It is only during cell division when chromosomes become highly condensed and visible under a microscope.
The five cell cycles are: Telophase (Cell wall pinches in, nuclear membranes are formed, two daughter cells are produced.) Interphase (You can cell the nucleolus, you can see uncoiled chromatin, you cannot see chromosomes.) Prophase (Chromatin uncoils, chromosomes appear, chromosomes duplicate to form sister chromatids, spindle forms between centrioles.) Metaphase (Chromosomes move to the middle of spindles.) Anaphase (Sister chromatids are pulled to opposite sides of cell, each chromatid is now a chromosome.)
Microscopes coupled with techniques used to separate them from inside the cell.
telophase. in this phase the chromosome disperse and you can't see the chromosome anymore throught the light microscope.
A diploid cell contains two sets of chromosomes, one set from each parent. In humans, a diploid cell has 46 chromosomes organized into 23 pairs. This is in contrast to a haploid cell, which has only one set of chromosomes.
Giemsa is the most common stain used to see banding patterns in chromosomes

DNA is replicated during interphase, and chromosomes form or condense during the prophase. So the genes and chromosomes are duplicated at the beginning of mitosis, during the interphase, although you can't see them as chromosomes until the prophase, before the cell splits.
