1. The new mutants must have been induced by nitrous acid.

2. This property must have been handed down to it from its wild ancestors notwithstanding that the tetraploid species we now have are self-fertile.

3. The lines we saw must have represented either the polar ends of the lipid molecules or the nonpolar carbon chains.

4. This is true concerning the astogeny, which must have taken another course to that in the genera mentioned previously.

5. They have acquired a new and special function that may have caused their excessive growth.

6. The muscles must have passed into the cavity and on contraction have had the effect of sliding.

7. A muscle arising from it must have passed outwards over the border of the distal face.

8. Later on it must have become cylindrical and finally more and more distinctly widened.

9. So Plank must have realized at this time that his formula had touched the foundations of our description of nature.

10. He must soon have found that his formula looked as if the oscillator could only contain discrete quanta of energy.

11. Genes have not been directly observed as yet, although recent experiments to be described in this book are bringing this possibility closer and closer to realization.

12. DNA is located exclusively within the nucleus and is entirely a chromosomol constituent, except in special circumstances to be discussed later.

13. The genes to be discussed in Chapters 4—8 are located on chromosomes.

14. This phenomenon, called position effect, was the first evidence I of gene interaction at the chromosome level, an exceedingly important problem to be discussed later.

15. This rather important assumption is borne out by experiments to be reported later.

16. This discussion is important because the same principles govern the structure of ribosomes, chromosomes, membranes, and other cell structures to be discussed in later chapters.

17. As for the role of DNA in storing and transmitting information to be used in protein synthesis it would appear that the specific sequence of the bases provides the code necessary for the determination of protein structure.

18. Is it possible to determine the specific sequence of amino acids in the polypeptide? Sanger was the first to show that this indeed could be done.

19. The conclusion to be made from this work is that the setback reactions in response to temperature shocks vary through the generations

20. The approach to these new dimensions may be a difficult one, and many of the ideas to be presented here may seem hazy and doubtful.
