Where is the information carried in the DNA

DNA stores information in a sequence of adenine, cytosine, guanine and thymine on a backbone of two deoxyribose molecules, which intertwine in a double helix. In nature, this information is read by RNA molecules and turned into proteins.

The information is carried in the middle structure of the DNA.

The 'rungs' between the two sides of the molecule are pairs of smaller molecules called nitrogenous base pairs, or nucleobases. There are 4 different bases, Adenine (A), Thymine (T), Cytosine (C), and Uracil (U). Each pairs up to a specific other base (A to T and C to U), and the order of which these bases are 'coded' to produce specific molecules that the cell will produce.
