Please help me with this question
replication fork
The DNA molecule forms a double helix. The linear DNA chromosomes of eukaryotes form a highly supercoiled double helix.

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

Normally, DNA forms a right-handed double helix but it can also come in other forms.
The supporting structure of the DNA double helix is called the sugar-phosphate backbone.
The chemical bond that holds the double helix together in DNA are the hydrogen bonds. Hydrogen bonds are the weakest making them perfect for DNA replication.
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.
