The two strands of a DNA molecule are held together by hydrogen bonds that occur between the nitrogen bases of both strands. The hydrogen bonds occur between the adenine and thymine nitrogen bases and between the cytosine and guanine nitrogen bases.
Hydrogen boding occurs between Nitrogen or oxygen atoms (containing lone pairs of electrons in their outer orbital) and hydrogen atoms.
They are weaker than covalent bonds but stronger than intermolecular forces.

What is the weak chemical bonds important in holding the dna double helix together is the?
The chemical bond that holds the double helix together in DNA are the hydrogen bonds. Hydrogen bonds are the weakest making them perfect for DNA replication.
How do alkali solutions denature DNA?
DNA has a double helix structure. This double helix structure exists, as the bases form hydrogen bonds (Adenine-Thymine form 2 hydrogen bonds and Guanine-Cytosine form 3 hydrogen bonds). In an alkali environment (mostly NaOH is used) the hydrogen bonds between the bases will be broken by the hydroxylic group (OH). Due to the breakage of the hydrogen bond, the double helix is broken, so two single DNA strands are obtained. Meaning the DNA is denatured.
What type of bonds make p DNA and where in DNA do you find these bonds?
The bonds are called hydrogen bonds. You can find these bonds in the nucleotides of DNA.
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 holds together the 2 strands of DNA?
Hydrogen bonds
Why are hydrogen bonds so so essential to the structure of DNA?
Hydrogen bonds hold the DNA bases together!
Explain how the structure of DNA relates to its function.?
The structure of DNA relates to its function greatly as the covalent bonds form the backbone of the DNA and provide the overall structure while the weak hydrogen bonds allow the DNA to unzip when needed to undergo replication.
What holds DNA bases together?
The bonds of the atom are covalent where as the bonds between the base pairs are hydrogen.
What bonds hold together DNA?
hydrogen bonds hold DNA together

How is the difference in bonds important to the function of DNA?
The difference in bonds is important to the function of DNA because it determines the stability and structure of the DNA molecule. DNA is made up of two strands, held together by hydrogen bonds between complimentary base pairs (adenine-thymine and cytosine-guanine). These bonds are relatively weak, allowing the DNA strands to separate during processes like DNA replication and transcription, which are essential for DNA's role in storing and transmitting genetic information.
What types of bonds are in DNA?
Hydrogen Bonds
