# Rna Transcription
|
||
|
|
|
||
|
|
Welcome to Rna Transcription on Exercism's Haskell Track.
|
||
|
|
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||
|
|
|
||
|
|
## Instructions
|
||
|
|
|
||
|
|
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`
|
||
|
|
|
||
|
|
Given invalid output, your program should return the first invalid character.
