How is the information within our dna structured?

DNA is shaped in a double helix with four different molecules: adenine (A), thymine (T), guanine (G), cytosine (C). A and T always go together, and C and G always go together and they never switch

The information within our DNA is structured into groups of three nucleotides called codons, which each code for one amino acid. DNA is shaped in a double helix, with two strands bound together in the middle. The outside of the helix is made of repeating sugar and phosphate molecules, called the sugar-phosphate backbone. The "rungs" of the DNA helix are the nucleotides. This is where the information is coded. Nucleotides can be one of four different molecules, adenine, guanine, cytosine, or thymine. The order of the nucleotides determines the information in the DNA sequence.
