Total nuclear dry mass
FIG. 7. Feulgen stain (DNA) and u.v. absorption at 2,536A (total nuclear nucleic acid)
measurements for individual mouse spontaneous tumour nuclei, plotted against the corresponding nuclear dry masses. All quantities are in arbitrary units.
A least squares analysis gives a correlation coefficient of 0*945 between total nucleic acid
and dry mass but a significantly lower correlation coefficient of 0-867 between D N A and
dry mass (t = 3-78 exceeding the value to be attained at the P = 0-001 level (t = 3-3)).
