WebMar 1, 2024 · By forming the double helix, the DNA gets the nitrogenous bases (these are AGTC) out of water and into the center where they don't have to interact with water so much. The simple answer is that nucleic acids will form double helicies in water (if they can) so as to get their more hydrophobic parts out of water. WebProteins control all biological systems in a cell, and while many proteins perform their functions independently, the vast majority of proteins interact with others for proper biological activity.
