Rna Transcription

Write a program that, given a DNA strand, returns 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:

Making the Test Suite Pass

Execute the tests with:

$ jasmine-node .

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.
