# Nucleotide Count
|
||
|
|
|
||
|
|
Given a single stranded DNA string, compute how many times each nucleotide occurs in the string.
|
||
|
|
|
||
|
|
The genetic language of every living thing on the planet is DNA.
|
||
|
|
DNA is a large molecule that is built from an extremely long sequence of individual elements called nucleotides.
|
||
|
|
4 types exist in DNA and these differ only slightly and can be represented as the following symbols: 'A' for adenine, 'C' for cytosine, 'G' for guanine, and 'T' thymine.

|
|
Here is an analogy:
|
||
|
|
- twigs are to birds nests as
|
||
|
|
- nucleotides are to DNA as
|
||
|
|
- legos are to lego houses as
|
||
|
|
- words are to sentences as...
