Biologists Must Constantly Keep In Mind That

Protein Synthesis Is A Central Problem For The Whole Of Biology, And That It Is In All Probability Closely Related To Gene Action.

I Also Suspect That Many Workers In This Field [molecular Biology] And Related Fields Have Been Strongly Motivated By The Desire, Rarely Actually Expressed, To Refute Vitalism.

It Is Not Easy To Convey, Unless One Has Experienced It, The Dramatic Feeling Of Sudden Enlightenment That Floods The Mind When The Right Idea Finally Clinches Into Place.

It Has Yet To Be Shown By Direct Biochemical Methods, As Opposed To The Indirect Genetic Evidence Mentioned Earlier, That The Code Is Indeed A Triplet Code.

The Balance Of Evidence Both From The Cell-free System And From The Study Of Mutation, Suggests That This Does Not Occur At Random, And That Triplets Coding The Same Amino Acid May Well Be Rather Similar.
