Francis Crick
Francis Harry Compton Crick OM FRSwas a British molecular biologist, biophysicist, and neuroscientist, most noted for being a co-discoverer of the structure of the DNA molecule in 1953 with James Watson. Together with Watson and Maurice Wilkins, he was jointly awarded the 1962 Nobel Prize in Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material"...

Francis Crick quotes about
believe discovery might
When you start in science, you are brainwashed into believing how careful you must be, and how difficult it is to discover things. There's something that might be called the 'graduate student syndrome'; graduate students hardly believe they can make a discovery.
believe years needs
Anybody who believes that the earth is less than 10,000 years old needs psychiatric help.
believe age earth
A knowledge of the true age of the Earth and of the fossil record makes it impossible for any balanced intellect to believe in the literal truth of every part of the Bible in the way that fundamentalists do.
stress believe dna
Rather than believe that Watson and Crick made the DNA structure, I would rather stress that the structure made Watson and Crick.
believe independent people
In the fullness of time, educated people will believe there is no soul independent of the body, and hence no life after death.
country believe years
One of the most frightening things in the Western world, and in this country in particular, is the number of people who believe in things that are scientifically false. If someone tells me that the earth is less than 10,000 years old, in my opinion he should see a psychiatrist.
act certain chain english-scientist messenger secondary seems since single virtually
It seems virtually certain that a single chain of RNA can act as messenger RNA, since poly U is a single chain without secondary structure.
assuming certain code deduce english-scientist information limited using
By using polymers of different composition and assuming a triplet code one can deduce limited information about the composition of certain triplets.
acid groups backbone
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.
minorities may acid
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.
simplicity tools use
While Occam's razor is a useful tool in the physical sciences, it can be a very dangerous implement in biology. It is thus very rash to use simplicity and elegance as a guide in biological research.
thinking arrogance ruthlessness
Jim and I hit it off immediately, partly because our interests were astonishingly similar and partly, I suspect, because a certain youthful arrogance, a ruthlessness, an impatience with sloppy thinking can naturally to both of us.
thinking class simplicity
For simplicity one can think of the + class as having one extra base at some point or other in the genetic message and the - class as having one too few.
determination acid would-be
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.
