What is the simplest way to describe a DNA structure?


So, I was wondering if anyone can explain to me what is the structure of the DNA and how could we see this structure.




DNA takes the form of a double helix. Each side of the helix has a sugar-phosphate backbone. This is connected to the opposite side through a nucleotide. A DNA molecule is formed from a strand of nucleotides containing cytosine, guanine, adenine, and thymine.
