# Rna Transcription
Given a DNA strand, return its RNA complement (per RNA transcription).
Both DNA and RNA strands are a sequence of nucleotides.
The four nucleotides found in DNA are adenine (**A**), cytosine (**C**),
guanine (**G**) and thymine (**T**).
The four nucleotides found in RNA are adenine (**A**), cytosine (**C**),
guanine (**G**) and uracil (**U**).
Given a DNA strand, its transcribed RNA strand is formed by replacing
each nucleotide with its complement:
* `G` -> `C`
* `C` -> `G`
* `T` -> `A`
* `A` -> `U`
## Elm Installation
Refer to the [Exercism help page](http://exercism.io/languages/elm) for Elm
installation and learning resources.
## Writing the Code
The first time you start an exercise, you'll need to ensure you have the
appropriate dependencies installed.
```bash
$ npm install
```
Execute the tests with:
```bash
$ npm test
```
Automatically run tests again when you save changes:
```bash
$ npm run watch
```
As you work your way through the test suite, be sure to remove the `skip <|`
calls from each test until you get them all passing!
