# 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", "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

## Setup

Go through the setup instructions for JavaScript to install the
 necessary dependencies:

http://exercism.io/languages/javascript/installation

## Running the test suite

The provided test suite uses [Jasmine](https://jasmine.github.io/).
You can install it by opening a terminal window and running the
following command:

```sh
npm install -g jasmine
```

Run the test suite from the exercise directory with:

```sh
jasmine protein-translation.spec.js
```

In many test suites all but the first test have been marked "pending".
Once you get a test passing, activate the next one by changing `xit` to `it`.
