The two chains of nucleotides in a DNA molecule are held together by hydrogen bonds between the bases. In DNA, cytosine forms three hydrogen bonds with guanine, and thymine forms two hydrogen bonds with adenine.
If you have a Biology textbook, you will find this answer in the caption on the bottom of page 284.
salts. namely the cation
DNA strands have long negatively charged phosphate backbones, and would want to repel each other. If you neutralize that charge with some salt, it will promote the two strands to come together and bond

the DNA polymerase III
Between nucleotides, there is a phosphodiester bond between the phosphate group of one nucleotide and the sugar of another nucleotide. Nucleotides (such as Adenine and Thymine) are held together on two strands of DNA through hydrogen bonding. This doesn't keep nucleotides together in a strand, but helps in the structure of two corresponding strands of DNA.
The mRNA molecule is completed by the formation of hydrogen bonds. These bonds are between the RNA nucleotides, which then separate from the DNA.
DNA
Phophodiester bonds are the one that connect the nucleotides next to each other on the same strand. Weak hydrogen bonds join the two complementary nucleotides and thus the two strands of the DNA together.
DNA and RNA
the DNA polymerase III
Without knowing what molecule and which nucleotides, it is impossible to answer your question.
The nucleotides bind with 2 hydrogen-bonds
Within the Dna double helix molecule Adenosine hydrogen binds only with Thymine while Cytosine hydrogen binds only with Guanine.
Nucleotides Four nucleotides are needed to make a DNA molecule.

A molecule of water, a molecule of hydrogen, a molecule of oxygen, a molecule of sugar... Actually more substances come in form of molecules than in atomic form.
A water molecule is formed when two hydrogen atoms bind covalently to a single oxygen atom.
DNA
Hydrogen is an atom but the hydrogen molecule is diatomic.H is a single Hydrogen atom, and H2 is a molecule.
