  "summary": "Nearly every cell in the human body contains essentially the same genetic information, yet different cells activate different genes. For regulatory proteins to reach these genes, DNA must be accessible. This accessibility depends not only on the genetic code itself but also on DNA's physical properties—its shape, flexibility and ability to interact with proteins.",
