Biological Molecules 



of biological atoms, certain molecules, can only 

 exist in conjunction with certain other combina- 

 tions. This is quite in accordance with the 

 teaching of physiologists regarding the inter- 

 dependence of the various organs of the body. 

 We have now reached the stage of the fertilised 

 ovum. According to our conception it is a series 

 or conglomeration of the precursors of the unit 

 characters of the adult. These precursors we 

 call biological molecules. Each is of a very com- 

 plex nature. Each seems to be composed of 

 several portions, only one of which will take 

 part in the building up of the body of the off- 

 spring, the other portions remaining latent. We 

 further conceive that it is possible for the various 

 radicles which compose these molecules to ar- 

 range themselves in various manners, and with 

 each new arrangement a different form of unit 

 character will be developed. These molecules, 

 then, are built up from radicles derived from 

 both parents, the most stable combinations being 

 formed and one portion of the molecule domin- 

 ating the whole. Under normal circumstances 

 this dominant portion of the molecule will give 

 rise to a character of a definite type. But it 

 seems that other factors may come into play and 

 cause a rearrangement of the radicles which 

 compose it, and this will result in the formation 

 of a unit character different from that to which it 

 would ordinarily give rise.
