# 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 To run the tests run the command `go test` from within the exercise directory. If the test suite contains benchmarks, you can run these with the `--bench` and `--benchmem` flags: go test -v --bench . --benchmem Keep in mind that each reviewer will run benchmarks on a different machine, with different specs, so the results from these benchmark tests may vary. ## Further information For more detailed information about the Go track, including how to get help if you're having trouble, please visit the exercism.io [Go language page](http://exercism.io/languages/go/about). ## Source Hyperphysics [http://hyperphysics.phy-astr.gsu.edu/hbase/Organic/transcription.html](http://hyperphysics.phy-astr.gsu.edu/hbase/Organic/transcription.html) ## Submitting Incomplete Solutions It's possible to submit an incomplete solution so you can see how others have completed the exercise.
