Covalent (double and single, as well as polar and non-polar) and Hydrogen bonds are found in the DNA molecule. The backbone of DNA is made of of Phosphate (PO43-) molecules and the sugar Deoxyribose (C5H10O4) Attatched to every sugar is a Base (C, G, A or T.) These are held together by single covalent bonds. Within the Phosphate, there is one double covalent bond (meaning two pairs of electrons are shared.). Note that O-C, O-P, H-N and O-H bonds will be polar. The two strands are held together by Hydrogen bonds. These are much weaker than a covalent bond and form between two molecules of opposite polarity. The two atoms, which are of positive and negative charge, are attracted to each other. That attraction is what constitutes a Hydrogen bond.

Hydrogen Bonds
In DNA molecules Which bonds are disrupted at high temperatures?
hydrogen bonds
What types of bonds holds the DNA bases together?
Strong hydrogen bonds.
DNA replication results in two identical DNA molecules. What role do DNA helicases have in DNA replication?
DNA helicases break the hydrogen bonds in the DNA molecule
What holds two strands of a DNA molecules to each other?
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.
Which enzyme is responsible for creating the covalent bonds that connect the sugar phosphate back bone of the new DNA molecules?
An enzyme called HELICASE breaks the sugar to phosphate bonds in DNA strands to initiate DNA replication and DNA transcription.
What kind of bond holds the two strands of a DNA molecule together?
hydrogen bonds. The other bonds are covalent bonds.
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.
