Eukaryotic Chromosomal Structure and Compaction. If the DNA from all 46 chromosomes in a human cell nucleus was laid out end to end, it would measure approximately two meters. However, the diameter would be only 2 nm. Considering that the size of a typical human cell is about 10 µm (100,000 cells lined up to equal one meter), …Using these microscopes, biologist Walter Flemming observed many tightly wound, elongated structures in cell nuclei. Later, it was found that chromosomes are made from DNA, the cell’s genetic material. Since then, scientists have proposed many possible ways that DNA molecules might fold into 3-D condensed chromosomes.
