Asingle chromosomal DNAmolecule contains about 4.5 million nucleotide units. If this molecule were extended so that the nucleotide units were 450 pm apart, what would be the length of the molecule? How does this compare with the length of the cell itself? What does this result suggest about the shape of the DNAmolecule?
