How many flagella can a cell have
WebWhen cells are ready for division, the chromatins can be further compressed to chromosomes, which can be visible with proper staining (we can not see the DNA molecules under a light microscope). We have 23 pairs of chromosomes (1-22, X, and Y), and the number will be doubled right before the cell division.
