      1. Rosalind Franklin`s and Maurice Wilkins`investigation of DNA structure by X-ray diffraction
        1. Rosalynd Franklin`s X-ray diffraction provided crucial evidence that DNA is a double helix
      2. Nucleosomes help the supercoil of DNA
        1. Some regions of DNA do not code for proteins but have other important functions
          1. Some regions of DNA do not code for proteins
            1. TOK
              1. Tandem repeats are used in DNA profiling
                1. Junk DNA
                  1. To what extent do the labels and categories used in the pursuit of knowledge affect the knowledge we obtain?
                2. Regulators of gene expression
                  1. Introns
