#Unit 1. Molecules and their Interaction Relevant to Biology

  1. Base-stacking is a non-covalent interaction that occurs between the relatively hydrophobic bases in the interior of the helix.

  2. Base-pairing is a non-covalent interaction that occurs between adjacent bases in the same strand of the DNA molecule.

  3. The hydrophilic sugar-phosphate groups are on the exterior of the helix where they can interact with each other.

  4. The deoxyribose rings form N-glycosidic bonds with the phosphate groups that link neighboring nucleotides.
