[B] Hydrogen bonds. and the hydroxyl (OH) group attached to the 3′
[C] Electrostatic bonds. carbon of the deoxyribose sugar in an adjacent
[D] Ionic bonds. nucleotide, forming what is known as the "sug-
[E] Phosphodiester bonds. ar-phosphate backbone" of DNA.
4. Peptide bonds. Bonds between amino acids
5. Hydrogen bonds. weak attraction between a hydrogen atom and
another atom
6. Electrostatic bonds. a chemical bond in which one atom loses an
electron to form a positive ion and the other
atom gains an electron to form a negative ion.

7. Ionic bonds. The ionic bond is the electrostatic force of at-
traction between a positively charged metal ion
and a negatively charged non-metal ion. Metals
form positive ions because they lose electrons
to become stable.
