Hydrogen bonds hold water molecules together. Hydrogen bonds are very strong, which accounts for the high boiling point of water (100˚C, 212˚F), and its ability to remain liquid water over such a huge range of temperatures.
The negative oxygen and positive hydrogen in water form hydrogen bonds with each other.
Water is held together by covalent bonds, specifically polar covalent bonds. These bonds result from the sharing of electrons between the oxygen and hydrogen atoms in a water molecule. The oxygen atom attracts the shared electrons more strongly than the hydrogen atoms, creating a slightly negative charge on the oxygen and slightly positive charges on the hydrogen atoms. This polarity of the water molecule allows for hydrogen bonding between adjacent water molecules, which contributes to the unique properties and behavior of water.

Peptide bonds hold amino acids together in a protein chain. Peptide bonds form through a condensation reaction between the carboxyl group of one amino acid and the amino group of another amino acid, releasing a water molecule in the process.
It's simply just energy.
Hydrogen bonds hold the nitrogenous bases together in a strand of DNA. These bonds form between complementary base pairs: adenine with thymine, and guanine with cytosine.
Hydrogen bonds hold the two strands of a DNA molecule together. These bonds form between complementary base pairs adenine-thymine and guanine-cytosine.
