# Rna Transcription Welcome to Rna Transcription on Exercism's Perl 5 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` ## Source ### Created by - @szabgab ### Contributed to by - @bistik - @kytrinyx - @m-dango - @rfilipo - @yanick ### Based on Hyperphysics - http://hyperphysics.phy-astr.gsu.edu/hbase/Organic/transcription.html
