The Double helix is actually made of repeating units called nucleotides
double helix, twisted ladder, spiral staircase.
double helix
-Two helices
nucleotides!
Double Helix :D
DNA is a double helix made of two strands linked together with hydrogen bonds.
the sides of a double helix are composed of a chain alternating between a phosphate and a deoxyribose (5 carbon) sugar.
double helix are made up of some monomeric compound like, nitrogenous compound of purine and pyrimidine, sugar and phosphate in case of DNA. In case of Protein alpha helix, which is also a double helical structure is made up of monomeric amino acids.
Double Helix
DNA, and the shape is also known as a double helix.
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
