***************** DNA Visualization ***************** .. tags:: short, artistic, science, scrolling Deoxyribonucleic acid is a tiny molecule that exists in every cell of our bodies and contains the blueprint for how our bodies grow. It looks like a double helix (a sort of twisted ladder) of pairs of nucleotide molecules: guanine, cytosine, adenine, and thymine. These are represented by the letters G, C, A, and T. DNA is a long molecule; it’s microscopic, but if it were stretched out, its 3 billion base pairs would be 2 meters long! This program is a simple animation of DNA. .. collapse:: dna_visualization.py .. literalinclude:: dna_visualization.py :language: python :linenos: https://inventwithpython.com/bigbookpython/project21.html
