Hydrogen bonding occurs beween Nitrogen, Oxygen, and Hydrogen.
Hydrogen Bond Donors:
The donor molecule of a hydrogen bond is covalently bound to the Hydrogen, therefore donating the Hydrogen to the acceptor.
Ex. R-NH O=C-R
indicates hydrogen bond
Hydrogen Bond Acceptors:
The acceptor receives the proton donation from the donor.

What do hydrogen bonds have to do with living beings?
Living things are mainly composed of water. Water molecules are held together by hydrogen bonds.
The weak chemical attraction between water molecules is what?
It is due to the hydrogen bonds holding water molecules together. Hydrogen bonds are the weekest bonds because they are the slight attraction between a positive and a negative charge.The reason water molecules have a positive and negative charge is because they are polar- the electrons of H2O are shared unevenly in their covalent bonds. A water molecule is held together with polar covalent bonds. Water molecules are held together by hydrogen bonds.
What is hydrogen peroxide held together by?
Hydrogen peroxide has covalent bonds between the atoms. The atoms are held together by those covalent bonds. There are van der Waals and dipole-dipole forces between the molecules.
Are Water molecules are held together by ionic bonds?
No, all molecules are held together by covalent bonds.
The two strands of a DNA molecule are held together by?
The strands of the DNA double helix are held together by hydrogen bonds

What type of molecules are bonded together by hydrogen bonds in DNA?
Nitrogenous bases are held together by hydrogen bonds, thus making them easier to separate during DNA replication.

Are Water molecules are held together by ionic bonds?
No, all molecules are held together by covalent bonds.
What holds the molecules in solid together?
Water molecules are held together by hydrogen bond which is formed between hydrogen of one molecule and oxygen of other molecule. H2O-----H-O-H
The two strands of a DNA molecule are held together by?
The strands of the DNA double helix are held together by hydrogen bonds
Adjacent water molecules are held together by bonds?
The intermolecular force that hold together adjacent water molecules are hydrogen bonds. Hydrogen bonds are the strongest type of intermolecular forces, but it is still relatively weak compared to ionic and covalent bonds. Hydrogen bonds occur because of the large difference between hydrogen atoms and the highly electronegative atoms such as F, N and O.
Each water molecule is joined to?
Each water molecule forms multiple hydrogen bonds with neighboring water molecules. These bonds are transient and easily and quickly shift among molecules.
What is adenine and guanine held together with?
The Cytosine, Guanine, Adenine and Thymine bases present in DNA are molecules that are held together by intermolecular hydrogen bonds. This bond occurs between an electronegative atom (known as a hydrogen bond acceptor) and a hydrogen atom attached to another electronegative atom (known as a hydrogen bond donor).
The bases of the two DNA chains are linked in the middle of molecules by?
Complementary bases in DNA are held together via hydrogen bonds. Between G and C there are three hydrogen bonds and between A and T there are two hydrogen bonds.
How are the nitrogen bases held together in the center of the DNA molecule?
The nitrogen bases bond A-T and C-G via hydrogen bonds. The bases are held together in the string by a backbone of alternating phosphate and sugar molecules.
