A three dimensional spiral.
No, RNA does not have a double helix structure like DNA.
Double Helix the structure of double coiled DNA
All of them. Tertiary is the overall 3D shape of the protein Quaternary is what proteins it is attached to and how Primary is the actual order of the amino-acids which make up the chain Secondary is the way that that chain coils or folds So 'helix' refers to the coiling of the chain. Hence it is the secondary structure.
Double Helix
No, RNA cannot form a double helix structure like DNA.
The supporting structure of the DNA double helix is called the sugar-phosphate backbone.
In the DNA. The term "double helix" refers to the structure of DNA.
The sugar-phosphate supporting structure of the DNA double helix is called the backbone. This is why the DNA is commonly referred to as a double helix.
In the DNA. The term "double helix" refers to the structure of DNA.
It's a double helix.
