these correlations are simply explained by postulating that dna has 2 major functions unrelated to its protein-coding capacity : ( 1 ) the control of cell volume by the number of replicon origins , and ( 2 ) the determination of nuclear volume by the overall bulk of the dna : cell growth rates are determined by the cell volume and by the area of the nuclear envelope available for nucleocytoplasmic transport of rna , which in turn depends on the nuclear volume and therefore on the dna content .
