Since the 4 bases are composed of 2 purines (adenine and guanine) and 2 pyrimidines (cytosine and thymine), 1 purine is bonded to 1 pyrimidine (e.g. guanine-cytosine; adenine-thymine). And the bond or linkage between this purine and pyrimidine is because of HYDROGEN BONDING.

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.
like the computer single helix is 1g ram double helix like 2g ram so double helix more stable
nitrogenous bases linked together
Double Helix the structure of double coiled DNA
DNA is a double helix, or a twisted ladder.

Chromosomes are build like that.Nucleus is a large organell with many components.

Normally, DNA forms a right-handed double helix but it can also come in other forms.
The whole DNA strand is a double helix.
