1. The behaviour observed was frequently different from that found with the simple homogeneous reactions.
2. Another system which provides evidence of the nucleic acid composition of hereditary material is that of the tobacco mosaic virus.
3. The mutants, tested for their ability to grow with any of these compounds, fell into three groups: those which could use only arginine, those that could use either arginine or citrulline, and those that could use any one of the three compounds equally well for growth.
4. The equations for activation are of the same form as those for a non-competitive inhibitor.
5. Diploid organisms possessing identical alleles at a given chromosomal location (locus) are called homozygotes, whereas those having different alleles at a locus are called heterozygotes.
6. These results are comparable to those found with the chromosomes of other organisms and indicate not only a doubleness of the genetic material but also a semiconservation of its organization.
7. Our understanding of the structure and biological function of RNA is more recent in origin and less complete than that of DNA.

9. In a lysogenic strain Jobin found that the latent period following UV-induction is of about 20 minutes longer than that of X-rays.
10. The test seems to be very convenient for analyzing the biological activity of complex radiations such as those which occur in places contaminated with radioactive substances.
11. The microspectrographically recordable changes, especially those of the nucleic acids, are more or less reflected in the gross chemical composition of samples.
