Go look at the model of DNA on the demonstration table. We have been presenting DNA as a straight ladder, but actually it is twisted on itself like a spiral staircase. This shape is called a heliz. Observe The Chromosome Normally DNA exists as loose strands (chromatin) in the nucleus of a cell. This nuclear DNA sends a message (RNA) to the ribosomes where protein and enzymes are synthesized. When stretched out, the length of one DNA molecule in a human cell is almost 4 cm. However, the cell itself is but a tiny fraction of that size. During cell reproduction the DNA must be able to move around. So it shortens its length by tightly coiling up. In doing so, the DNA strands become wider and are visible under a microscope.…arrow_forward
