Comments P.211 left column bottom paragraph: "For example, in Prorocentrum micans, which has 65 chromosomes, the DNA amount per cell is 7.0 × 10^10 nucleotide pairs for a nuclear volume of 3,450 μm^3 and a chromosome volume of 20 μm^3. In Crypthecodinium cohnii, which has 95−100 chromosomes, the DNA amount per cell is 1.4 × 10^10 nucleotide pairs for a nuclear volume of 690 μm^3 and a chromosome volume of 2.6 μm^3 [primary source]. These measurements demonstrate the extraordinary compaction of DNA."
