of the origin of those compounds ^vhich are specific to living 

 things, the proteins with their enzymic activities and the 

 nucleoproteins with their capacity for self reproduction. Such 

 authors also see the primary development of these compounds 

 as the key to the understanding of the origin of life. These 

 arguments do not, however, usually amount to more than 

 individual general declarations and it seems to us that such 

 an approach to the problem which we are considering is 

 wrong. 



The origin of proteins, enzymes, nucleoproteins and other 

 substances specific to living things cannot simply be based 

 on those laws which we have been using up till now. There 

 must first have arisen a new specific organisation and after- 

 wards, on the basis of it, the substances appeared, not vice 

 versa. To resolve this vexed question we must now leave, for 

 a while, the approach to the problem which we have hitherto 

 followed. Before studying the further stages in the develop- 

 ment of matter on the ^vay to the emergence of life we must 

 learn about the structure and properties of proteins, nucleic 

 acids and other biologically important compounds which 

 constitute the basis of present-day living matter.
