The backbone of DNA is made up of a sugar-phosphate-sugar-phosphate pattern that repeats itself.

What is the structure of DNA?

  • DNA is a nucleotide-based double helical structure. Hydrogen bonds hold the two helices together. A sugar-phosphate backbone is also present in the DNA.
  • Nucleotides are the building blocks of DNA and are composed of three components: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base.
  • A double helix is a twisted ladder-like structure composed of two interconnected strands winding around each other. Each strand has a sugar (deoxyribose) and phosphate backbone that alternates. Each sugar is connected to one of four bases: adenine (A), cytosine (C), guanine (G), or thymine (T).
  • Understanding the structure and function of DNA has revolutionized disease pathway research, assessing an individual's genetic susceptibility to specific diseases, diagnosing genetic disorders, and developing new drugs. It is also essential for pathogen identification.
