Web12 okt. 2024 · The two helical strands are connected through interactions between pairs of nucleotides, also called base pairs. How many total hydrogen bonds are holding the two strands together? The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together. WebHydrogen bonds are not 'real' bonds in the same way that covalent, ionic, and metallic bonds are. Covalent, ionic, and metallic bonds are intramolecular electrostatic attractions, meaning they hold atoms together within a molecule. On the other hand, hydrogen bonds are intermolecular forces meaning they occur between molecules.
