# 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` ## Setup Go through the setup instructions for JavaScript to install the necessary dependencies: http://exercism.io/languages/javascript/installation ## Making the Test Suite Pass Execute the tests with: jasmine .spec.js Replace `` with the name of the current exercise. E.g., to test the Hello World exercise: jasmine hello-world.spec.js In many test suites all but the first test have been skipped. Once you get a test passing, you can unskip the next one by changing `xit` to `it`. ## Source Rosalind [http://rosalind.info/problems/rna](http://rosalind.info/problems/rna) ## Submitting Incomplete Solutions It's possible to submit an incomplete solution so you can see how others have completed the exercise.
