- Rosalind Franklin`s and Maurice Wilkins`investigation
of DNA structure by X-ray diffraction
- Rosalynd Franklin`s X-ray diffraction provided
crucial evidence that DNA is a double helix
- Nucleosomes help
the supercoil of DNA
- Some regions of DNA do not code for proteins
but have other important functions
- Some regions of DNA do not code for proteins
- TOK
- Tandem repeats are used in DNA profiling
- Junk DNA

pursuit of knowledge affect the knowledge we obtain?
- Regulators of gene expression
- Introns
- Telomeres
