One a feature of the structure of all dna molecules is the

The structure of the DNA is ideal for the complex function that it plays.

Some of the features of the structure of all DNA molecules are:

Sugar- phosphate backbone:

The sugar- phosphate backbone is ideal for providing the DNA a ladder- like shape which is essential for its functions.

Hydrogen bonds:

The hydrogen bonds present in the nucleotides keep both the DNA strands intact. If the hydrogen bonds were not present then the double helix would not have been able to form.

Coiling:

The structure of the DNA is coiled and super coiled so that it can fit into an organism.

hope this !

answer: i don't know

explanation:

you need to provide a picture, otherwise i can't tell you.

if you can provide one, i'd be more than happy to you with this!
