# 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!
