double helix
Double Helix
Normally, DNA forms a right-handed double helix but it can also come in other forms.
In the DNA. The term "double helix" refers to the structure of DNA.
Some parts of a protein can have a helical structure - one of the most common secondary structures in proteins is the alpha helix.However, helix - especially double helix - will probably be more often used in the description of DNA, so be careful not to mistake the two.
double helix
When two complimentary threads of DNA coil round each other they form a double helix pattern. They can coil up further to form chromosomes.
Double Helix
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.
Spiral, coil, volute, whorl.
Double Helix the structure of double coiled DNA
Normally, DNA forms a right-handed double helix but it can also come in other forms.
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.
