Protein Translation

Write a program that will translate RNA sequences into proteins.

Lets write a program that will translate RNA sequences into proteins. [general ref](http://en.wikipedia.org/wiki/Translation_(biology)

RNA can be broken into three nucleotide sequences called codons, and then translated to a polypeptide like so:

RNA: "AUGUUUUCU" => translates to

Codons: "AUG", "UUU", "UCU" => which become a polypeptide with the following sequence =>

Protein: "Methionine", "Phenylalanine", "Serine"

There are 64 codons which in turn correspond to 20 amino acids; however, all of the codon sequences and resulting amino acids are not important in this exercise. If it works for one codon, the program should work for all of them. However, feel free to expand the list in the test suite to include them all.

There are also four terminating codons (also known as 'STOP' codons); if any of these codons are encountered (by the ribosome), all translation ends and the protein is terminated.

All subsequent codons after are ignored, like this:

RNA: "AUGUUUUCUUAAAUG" =>

Codons: "AUG", "UUU", "UCU", "UAG", "AUG" =>

Protein: "Methionine", "Phenylalanine", "Serine"

Note the stop codon terminates the translation and the final methionine is not translated into the protein sequence.

Below are the codons and resulting Amino Acids needed for the exercise.

Codon Protein
AUG Methionine
UUU, UUC Phenylalanine
UUA, UUG Leucine
UCU, UCC, UCA, UCG Serine
UAU, UAC Tyrosine
UGU, UGC Cysteine
UGG Tryptophan
UAA, UAG, UGA STOP

To run the tests simply run the command go test in the exercise directory.

If the test suite contains benchmarks, you can run these with the -bench flag:

go test -bench .

For more detailed info about the Go track see the help page.
