The single helix is comprised of "The Sugar - Phosphate Backbone". No Nitrogen there.
Any nitrogen that may be present resides then in the nucleotides.

What is the shape of the DNA molecule known as?
Double Helix :D
What type of structure is the DNA?
Double Helix
What molecule has the shape of a double strand helix?
DNA, and the shape is also known as a double helix.
What is the name for the DNA structure?
Normally, DNA forms a right-handed double helix but it can also come in other forms.
Which part of DNA is double helix?
The whole DNA strand is a double helix.
what is the shape of a DNA?
double helix
Enzymes that open the double helix by breaking hydrogen bonds between nitrogen bases is what?
Helicase.
In the Watson-Crick model of a double helix the steps of the spiral staircase are composed of?
Nitrogen Bases.
What are thymines?
Thymine is a nitrogen base that is wound up inside the double helix of DNA. It pairs with Adenine.
Why nitrogen atom does not contain double bond?
A nitrogen atom contains three valence electrons so a nitrogen molecule N2 will form a triple covalent bond.
What is nitrogen bases role in DNA?
the hydrogen bonds btw nitrogenous bases leads to stability of the double helix
What is the shape of the DNA molecule known as?
Double Helix :D
What is the overall structure of the DNA molecule?
The physical structure is called a double-helix.
What type of structure is the DNA?
Double Helix
What molecule has the shape of a double strand helix?
DNA, and the shape is also known as a double helix.
What is a double helix DNA or RNA?
Both DNA and RNA can exist in the double helix form, but only DNA is completely stable as a double helix. The double helix RNA is usually only short "hairpin" sections folding back on itself, never the long essentially linear form of double helix DNA.
True or false Helicases unwind the double helix of DNA by breaking the nitrogen bonds that link the hydrogen bases?
Hydrogen bonds.
