Phosphate and sugar.
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.
Its when two monosaccharide molecules can chemically join to form a double helix therefore forming a molecular bond which is consider a isomerism.
DNA is organized in a double-helix fashion.
It takes the form of a double helix. Basically it looks like a twisted ladder.
When two complimentary threads of DNA coil round each other they form a double helix pattern. They can coil up further to form chromosomes.
The rungs of the DNA double helix are made up of alternating deoxyribose sugar molecules and phosphate molecules. Please refer to the related link below.

DNA has two polynucleotide molecules that spiral around an imaginary axis to form a double helix. only certain bases in the double helix are compatible with each other. Adenine pairs with thymine and guanine pairs with cytosine.
a double helix
I'm assuming you mean the double helix "ladder-like" formation of a strand of DNA. The sides of the structure are essentially a phosphate-deoxyribose backbone.
The DNA strands are held together by hydrogen bonds between complimentary base pairs.
DNA is organized in a double-helix fashion.
Scientists by the name of James Watson and Francis Crick discovered DNA to be in the form of a double helix.
Two single chains bond together. The bonded chains twist together to form a double helix.
Watson and Crick deiscovered the double helix shape of DNA
