# 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.
