The sequence of nucleotides, coded in triplets (codons) along the mRNA, that determines the sequence of amino acids in protein synthesis. The DNA sequence of a gene can be used to predict the mRNA sequence, and the genetic code can in turn be used to predict the amino acid sequence.

This is the $64,000 question, what is the genetic code? The thrust of this rambling page is that we don't really know the answer to this exceptionally important question. The genetic code clearly must involve the process of making protein based on information in DNA, but precisely how is this done? Here are some equally important and related questions:
What is life?
What is DNA?
What is a protein?
Life, as described by Erwin Schrodinger, is an aperiodic crystal. DNA is a crystal, and so is protein. Note the pattern. The cleanest view then to the nature of the genetic code is that it is a complex algorithm through which one crystal is formed according to specific properties of another, sovereign crystal. This then requires a language where two crystal types must somehow communicate information. Tough job, don't you think? It's hard to believe there's a way to consistently do it!
Science works by simplifying complexity, but in the case of the genetic code we have oversimplified. The chest-beating certainty of the scientific community has obfuscated the fact that we still do not understand nature's nifty crystal-forming algorithm affectionately referred to as the genetic code. We have mastered the well-worn correlation data between sequential components of each crystal type, but this is not the same as the language that communicates genetic information into a fully formed crystal. Science has dogmatically insisted that they are the same thing, but where's the proof? I doubt that we'll ever see it.
News flash: The earth rotates around the sun. Note to astronomers: lose the epicycles.
All life on this planet is based on a genetic code. It is a system that somehow defines the construction of living things by directing the processes of molecular synthesis and replication. In 1953 James Watson and Francis Crick described a double helix as the structure of a huge molecule called DNA, which was known to reside in the cell nucleus and store the secrets of the genetic code. Excitement grew, and by 1960 leaders in science were predicting that nature would be laid bare within a year, creating justifiable fears. If man actually controlled the genetic code, what would happen to life on earth? Salvadore Dali seemed to anticipate man’s dominion over nature and its relationship to a higher truth, as shown in his painting The Temptation of Saint Anthony.
The predictions and accompanying fears proved unfounded, however, since the code wasn’t completely “broken” for another ten years. Entirely synthetic life has yet to be created, and today, despite tremendous strides in genetic engineering, there is a general disaffection with the code. It appears that the code alone was not enough to allow man dominion over nature. The full glory of protein synthesis remains a mystery, so we have now moved “past the code” and on to proteins themselves. According to conventional thinking, the genetic code is so simple and buttoned down that its logical foundation appears remarkably trivial. Instead, today’s glamour boy is the protein – the idol to proteomics. It is the study of proteins and their many eccentric habits of folding that dominates the search. Proteins are so devilishly complex that “Breaking the protein” makes “breaking the code” look like child’s play. Fortunately, we have a tremendous amount of technology to help with the task as compared to 1960, and some of the greatest scientific minds are focused on a solution.
Surprise!
The genetic code is child’s play.
Enter the child.
A funny thing happened on our way to dominion: somebody… everybody forgot to “break” the other half of the code. A central premise of these pages is that the genetic code is far different from our conventional view of it. The genetic code somehow makes proteins, not just sequences of amino acids. (No, they are not the same thing.) I attempt through these writings to illustrate this “obvious” fact, and the implications of having missed it. I also intend to swing a machete in the general direction of any sacred cow that ambles into view.
That’s how children are – childish.
Starting with a modified version of the standard Watson-Crick table we see the set of codons and amino acids that are a part of the genetic code. From the conventional perspective, the genetic code starts and ends with pairing codons and amino acids.

Its the sequence you DNA uses A_T G_C those are the olny two conditions everything else like how many time each part is repeated oand when is a code the only your body holds and every human being has there own seperate code that nobody can hack, but they can isolate ceratian sequences and manipulate them. Thats wat aliens do, lol.

A,T,C,G.
A pairs up with T
C pairs up with G
The coded string then contains the information for amino acid synthesis.
