Jim And I Hit It Off Immediately,

It Would Appear That The Number Of Nonsense Triplets Is Rather Low, Since We Only Occasionally Come Across Them. However This Conclusion Is Less Secure Than Our Other Deductions About The General Nature Of The Genetic Code.

A Theory Should Not Attempt To Explain All The Facts, Because Some Of The Facts Are Wrong

It Is One Of The More Striking Generalizations Of Biochemistry - Which Surprisingly Is Hardly Ever Mentioned In The Biochemical Textbooks - That The Twenty Amino Acids And The Four Bases, Are, With Minor Reservations, The Same Throughout Nature.

It Now Seems Certain That The Amino Acid Sequence Of Any Protein Is Determined By The Sequence Of Bases In Some Region Of A Particular Nucleic Acid Molecule.

Attempts Have Been Made From A Study Of The Changes Produced By Mutation To Obtain The Relative Order Of The Bases Within Various Triplets, But My Own View Is That These Are Premature Until There Is More Extensive And More Reliable Data On The Composition Of The Triplets.
