# Nucleotide Count Given a DNA string, compute how many times each nucleotide occurs in the string. DNA is represented by an alphabet of the following symbols: 'A', 'C', 'G', and 'T'. Each symbol represents a nucleotide, which is a fancy name for the particular molecules that happen to make up a large part of DNA. Shortest intro to biochemistry EVAR: - twigs are to birds nests as - nucleotides are to DNA and RNA as - amino acids are to proteins as - sugar is to starch as - oh crap lipids I'm not going to talk about lipids because they're crazy complex. So back to nucleotides. DNA contains four types of them: adenine (`A`), cytosine (`C`), guanine (`G`), and thymine (`T`). RNA contains a slightly different set of nucleotides, but we don't care about that for now. ## Elm Installation Refer to the [Exercism help page](http://exercism.io/languages/elm) for Elm installation and learning resources. ## Writing the Code The first time you start an exercise, you'll need to ensure you have the appropriate dependencies installed. ```bash $ npm install ``` Execute the tests with: ```bash $ npm test ``` Automatically run tests again when you save changes: ```bash $ npm run watch ``` As you work your way through the test suite, be sure to remove the `skip <|` calls from each test until you get them all passing! ## Source The Calculating DNA Nucleotides_problem at Rosalind [http://rosalind.info/problems/dna/](http://rosalind.info/problems/dna/) ## Submitting Incomplete Solutions It's possible to submit an incomplete solution so you can see how others have completed the exercise.
