One reason DNA chains twist into a double helix is for the purpose of
It has two, the reason being is that it has to form into the famous "twisting" pose.
Double helix - with a deoxyribose (sugar) and phosphate backbone, and nitrogenous bases in the centre.
All i know is that it forms a double helix
A DNA molecule has the shape of a double-stranded 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.
DNA chain twists so that the bases are closer together in the double helix. The DNA chain also takes up less space this way.
Normally, DNA forms a right-handed double helix but it can also come in other forms.
hydrogen bonds hold it together
DNA is a double helix made of two strands linked together with hydrogen bonds.
double helix
nucleotides
Two single chains bond together. The bonded chains twist together to form a double helix.
Double Helix :D

Double Helix
First of all, RNA is a single helix. It isn't really similar to the DNA in the obvious shape. In DNA there two long polynucleotides chins which are right handed double helix. the chains are antiparallel to each other. while in RNA there is only a single chain.
DNA, and the shape is also known as a double helix.
