"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."

"The Peace of Wild ThingsWhen despair for the world grows in meand I wake in the night at the least soundin fear of what my life and my children's lives may be,I go and lie down where the wood drakerests in his beauty on the water, and the great heron feeds.I come into the peace of wild thingswho do not tax their lives with forethoughtof grief. I come into the presence of still water.And I feel above me the day-blind starswaiting with their light. For a timeI rest in the grace of the world, and am free."
"Then the immortal heart of the woods will beat against ours and its subtle life will steal into our veins and make us its own forever, so that no matter where we go or how widely we wander we shall yet be drawn back to the forest to find our most enduring kinship."
"Who would dare assign to art the sterile function of imitating nature?"
"Mountains in the distance remind me of you."
"No mountain is of any appreciable height to break the curve of the sphere."
"Revenge is a kind of wild justice, which the more a man's nature runs to, the more ought law to weed it out."
"It was still twilight when they reached the flat rock. They sat, and the stone still held the warmth of the day's sun. At first there were only occasional sparkles, but as it got darker Chuck was lost in a daze pf delight as a galaxy of fireflies twinkled on and off, flinging upward in a blaze of light, dropping earthward like falling stars, moving in contiuous effervescent dance."
"Dark night knows what full moon requires When all your love my heart acquiresCelestial bodies no more faded Life makes sound, silence invaded."

"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."
"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."
"It now seems very likely that many of the 64 triplets, possibly most of them, may code one amino acid or another, and that in general several distinct triplets may code one amino acid."
"It seems likely that most if not all the genetic information in any organism is carried by nucleic acid - usually by DNA, although certain small viruses use RNA as their genetic material."
"We are sometimes asked what the result would be if we put four +'s in one gene. To answer this my colleagues have recently put together not merely four but six +'s."
"The meaning of this observation is unclear, but it raises the unfortunate possibility of ambiguous triplets; that is, triplets which may code more than one amino acid. However one would certainly expect such triplets to be in a minority."
"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."
"A comparison between the triplets tentatively deduced by these methods with the changes in amino acid sequence produced by mutation shows a fair measure of agreement."
"How is the base sequence, divided into codons? There is nothing in the backbone of the nucleic acid, which is perfectly regular, to show us how to group the bases into codons."
"Unfortunately it makes the unambiguous determination of triplets by these methods much more difficult than would be the case if there were only one triplet for each amino acid."
