# 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`
## Running the tests
1. Go to the root of your PHP exercise directory, which is `<EXERCISM_WORKSPACE>/php`.
To find the Exercism workspace run
% exercism debug | grep Workspace
1. Get [PHPUnit] if you don't have it already.
% wget --no-check-certificate https://phar.phpunit.de/phpunit.phar
% chmod +x phpunit.phar
2. Execute the tests:
% ./phpunit.phar rna-transcription/rna-transcription_test.php
