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.
DNA and RNA are organic substances that are composed of nucleotides. A nucleotide contains a sugar, a phosphate group, and an organic base.
The mRNA molecule is completed by the formation of phosphodiester bonds between the RNA nucleotides during the process of transcription. This results in a single-stranded molecule that carries the genetic information from DNA to the ribosome for protein synthesis.
A molecule of RNA contains one strand of nucleotides.
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 whole strand is called a double helix a individual molecule made up of... a sugar a phosphate a base is called necleotide.

DNA and RNA are organic substances that are composed of nucleotides. A nucleotide contains a sugar, a phosphate group, and an organic base.
Without knowing what molecule and which nucleotides, it is impossible to answer your question.
Any molecule that contains hydrogen and carbon is an organic compound. If the molecule contains no other elements, it is also a hydrocarbon.
Hydrogen bonds
Within the Dna double helix molecule Adenosine hydrogen binds only with Thymine while Cytosine hydrogen binds only with Guanine.
The base of the nucleotides
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.
The mRNA molecule is completed by the formation of phosphodiester bonds between the RNA nucleotides during the process of transcription. This results in a single-stranded molecule that carries the genetic information from DNA to the ribosome for protein synthesis.
Ribonucleic acid
In nucleotides, sugars are joined to phosphate groups by phosphodiester bonds. This bond is formed between the 5' carbon of one sugar molecule and the 3' carbon of another sugar molecule, creating a sugar-phosphate backbone in DNA and RNA strands.
