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.

FRANCIS CRICK -
My own prejudices are exactly the opposite of the functionalists’: “If you want to understand function, study structure”.
