The incorporation of [<sup>32</sup>P]ATP is enhanced by the addition of an ATP-generating system.

Successive extractions at any one temperature produce extracts whose ribonucleic acid content decreases markedly. The analysis of the specific activity of extracted nuclear ribonucleic acid indicates two fractions: (1) a relatively low specific-activity fraction obtained at 25, 40 and 50°; and (2) a relatively high specific-activity fraction obtained at 65 and 75°, temperatures at which measurable amounts of deoxyribonucleic acid are also extracted.</p><p>It is demonstrated that InCl<sub>3</sub> at appropriate concentration and ionic strength, effectively precipitates all soluble ribonucleic acid as well as all deoxyribonucleic acid as the indic nucleates.

Higher ratios of the moderately lysine-rich histones (Fraction 2b) and of the arginine-rich histones (Fractions 2a and 3) were required. Complete inhibition was observed only at ratios of histone-DNA of 2:1 and higher. Histone stabilizes the helical molecule of DNA towards heat denaturation.
