Answer:

Eukaryotic chromosomes become visible with a light microscope before cell division because they condense. Explanation: This is necessary in order to move the chromosomes during the mitosis without becoming damaged (broken or tangled) while they are distributed to the daughter cells. The DNA in this condensed state can no be transcribed into RNA during mitosis. Remember that mitosis is the foundation of growth, tissue repair and asexual reproduction and its primary result is the transfer of a parent cell's genome into two genetically identical daughter cells.
