Covalent Bonds
The polar covalent bond between the hydrogen and oxygen atoms holds it together.
A covalent bond holds the hydrogen and chlorine atoms together in a molecule of hydrochloric acid (HCl). This type of bond involves a sharing of electrons between the atoms.
The chemical bond that holds together the complementary nucleotide bases in DNA is called a hydrogen bond. These bonds form between specific pairs of bases (A-T and G-C) and help stabilize the double helix structure of the DNA molecule.
