DNA

Caption

One example of how hydrophobic interactions are critical to biomedical applications can be found in how DNA base pairs on the two strands are drawn together to form a double helix. The basic structure of a DNA molecule is a hydrophilic backbone and a hydrophobic inner region of nitrogenous bases (adenine, guanine, thymine, and cytosine). These molecular hydrophobic forces repel the water between them which drives the bases towards each other.
