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 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, water molecules are held together by covalent bonds, where electrons are shared between the atoms. Ionic bonds involve the transfer of electrons between atoms of different elements. Water is a polar molecule due to the unequal sharing of electrons, resulting in a slightly negative oxygen atom and slightly positive hydrogen atoms.
The two strands of DNA molecules are held together by?
hydrogen bonds between complementary nitrogenous bases.
Adjacent water molecules are held together by bonds?
Water molecules are held together by hydrogen bonds. These bonds are formed between the partially positive hydrogen atom of one water molecule and the partially negative oxygen atom of another water molecule. This cohesive force gives water its unique properties, such as high surface tension and cohesion.
How are nucleic acids held together?
Nucleic acids are held together by phosphodiester bonds between the sugar and phosphate groups of adjacent nucleotides in the backbone of the molecule. Additionally, hydrogen bonds between nitrogenous bases in complementary strands help stabilize the double-stranded structure of DNA or RNA.
What do hydrogen bonds have to do with living beings?
Hydrogen bonds are essential for the structure and function of biological molecules like DNA, proteins, and water in living beings. They help maintain the shape of biomolecules, facilitate interactions between molecules, and are crucial for processes like protein folding, DNA replication, and maintaining the unique properties of water essential for life.
The weak chemical attraction between water molecules is what?
The weak chemical attraction between water molecules is called hydrogen bonding. This occurs due to the slightly positive charge on the hydrogen atoms of one water molecule attracting the slightly negative charge of the oxygen atom of another water molecule. Hydrogen bonding is responsible for many of water's unique properties.
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.
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, water molecules are held together by covalent bonds, where electrons are shared between the atoms. Ionic bonds involve the transfer of electrons between atoms of different elements. Water is a polar molecule due to the unequal sharing of electrons, resulting in a slightly negative oxygen atom and slightly positive hydrogen atoms.
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 two strands of a DNA molecule are held together by hydrogen bonds between complementary nitrogenous bases. Adenine pairs with thymine, and guanine pairs with cytosine. This base pairing allows the two strands to twist together in a double helix structure.
Adjacent water molecules are held together by bonds?
Water molecules are held together by hydrogen bonds. These bonds are formed between the partially positive hydrogen atom of one water molecule and the partially negative oxygen atom of another water molecule. This cohesive force gives water its unique properties, such as high surface tension and cohesion.
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?
Adenine and guanine are held together with hydrogen bonds in a DNA molecule. These hydrogen bonds form between specific nitrogenous base pairs, with adenine pairing with thymine and guanine pairing with cytosine.
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.
