# 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.
## Running tests
Execute the tests with:
```bash
$ elixir bob_test.exs
```
(Replace `bob_test.exs` with the name of the test file.)
### Pending tests
In the test suites, all but the first test have been skipped.
Once you get a test passing, you can unskip the next one by
commenting out the relevant `@tag :pending` with a `#` symbol.
For example:
```elixir
# @tag :pending
test "shouting" do
assert Bob.hey("WATCH OUT!") == "Whoa, chill out!"
end
```
Or, you can enable all the tests by commenting out the
`ExUnit.configure` line in the test suite.
```elixir
# ExUnit.configure exclude: :pending, trace: true
```
