# 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`

## Resources

Remember to check out the Perl 6 [documentation](https://docs.perl6.org/) and
[resources](https://perl6.org/resources/) pages for information, tips, and
examples if you get stuck.

## Running the tests

There is a test script included with the exercise; a file with the extension
`.t`. You can run the test script for the exercise by executing the command
`prove . --exec=perl6` in the exercise directory. You can also add the `-v` flag
e.g. `prove . --exec=perl6 -v` to display all tests, including any optional
tests marked as 'TODO'.
