# 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... ## Hints This exercise requires the use of a Dictionary.
