"A final proof of our ideas can only be obtained by detailed studies on the alterations produced in the amino acid sequence of a protein by mutations of the type discussed here"

This quote by Francis Crick is describing the concept that mutations in the amino acid series of a protein can be studied in order to gain a better understanding of the protein's structure and function. Crick is recommending that the only way to really show the validity of these concepts is to perform detailed research studies on the modifications that take place in the amino acid sequence of a protein when mutations happen. This quote highlights the importance of studying the effects of mutations on proteins in order to acquire a better understanding of how proteins work and how they can be controlled. By studying the results of anomalies on proteins, researchers can get insight into how proteins are structured and how they communicate with other molecules. This knowledge can then be used to establish treatments for diseases and to create new drugs. Eventually, Crick's quote highlights the importance of studying the impacts of anomalies on proteins in order to get a better understanding of how proteins work and how they can be controlled.
