# Protein Translation Translate RNA sequences into proteins. 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 three 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", "UAA", "AUG"` => Protein: `"Methionine", "Phenylalanine", "Serine"` Note the stop codon `"UAA"` 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 Learn more about [protein translation on Wikipedia](http://en.wikipedia.org/wiki/Translation_(biology)) ## Rust Installation Refer to the [exercism help page][help-page] for Rust installation and learning resources. ## Writing the Code Execute the tests with: ```bash $ cargo test ``` All but the first test have been ignored. After you get the first test to pass, remove the ignore flag (`#[ignore]`) from the next test and get the tests to pass again. The test file is located in the `tests` directory. You can also remove the ignore flag from all the tests to get them to run all at once if you wish. Make sure to read the [Modules](https://doc.rust-lang.org/book/second-edition/ch07-00-modules.html) chapter if you haven't already, it will help you with organizing your files. ## Feedback, Issues, Pull Requests The [exercism/rust](https://github.com/exercism/rust) repository on GitHub is the home for all of the Rust exercises.
