Question

Why aren't chromosomes always visible?

Answer 1

Chromosomes aren't always visible, because they usually sit uncoiled, in pairs, as loose strands called chromatin.

Answer 2

Under normal circumstances chromosomes are not visible because they are too tiny to be seen by the human eye. Much like bacteria are to tiny to be seen. But when a cell starts to divide the chromosomes will condense because they need to be able to cope with large mechanical forces dragging them into 2 different daughter cells. This causes the chromosomes to become much denser than when the cell is not dividing and they will become visible. You could compare this to sweeping together a lot of bacteria to make a visible glob.
