Imagine DNA as a ladder. The sugar and phosphate pattern are the vertical parts. Nucleobases are paired together and form the steps. A sugar, phosphate group and nucleobase form a nucleotide and each vertical column of the ladder runs in an opposite direction. One other feature is that a Purine must be paired with a Pyrimidine which is why A is always with T and C is always with G.

Does DNA have bases on the interior of the double helix?
Yes. Indeed, while the Exterior of DNA is the sugar-phosphate backbone, the Interior of the DNA double-helix is where the [nucleotide] bases reside.
What part of the twisted ladder or double helix of DNA is made up for the nucleotide bases?
The part of the twisted ladder or double helix of DNA is made for the nucleotide bases are adenine always pairs up with thymine on the other side, guanine always pairs up with cytosine.
Who discovered the basic shape and structure from Nucleotide?
James Dewey Watson discovered it, and its shape is a double helix.
The structure of DNA is described as a?
Double helix - with a deoxyribose (sugar) and phosphate backbone, and nitrogenous bases in the centre.
Which nucleotide is not incorporated into the structure of the DNA helix?
uracil
What is the overall structure of the DNA molecule?
The physical structure is called a double-helix.
Structure of DNA molecules?
DNA is made up of many nucleotides. These are a sugar-phosphate backbone and nitrogenous bases. The two strands form a double helix (a spiral) with the nitrogenous bases in the middle, forming H-bonds with each other.
What type of structure is the DNA?
Double Helix
Explain how a double helix is similar to a spiral staircase?
Two strands of DNA intertwined together and twisted to form a double helix. The sugar phosporous backbone is like the side of the stairs and the nucleotide bases are like the steps of the stairs.
What is the model of the structure of DNA called?
double helix, twisted ladder, spiral staircase.
In the double helix shape of DNA what series of nucleotides would match the nucleotide series g-a-c-t?
double helix
How is double helix used in a sentence?
Double Helix the structure of double coiled DNA
