While sugar (deoxyribose) and phosphate molecules form the backbone of DNA, they don't code for genetic information. The genetic code is actually carried by the sequence of nitrogenous bases attached to the sugar molecules.
Here's a breakdown:
* DNA structure: DNA is a double helix, with two strands running in opposite directions. Each strand consists of a sugar-phosphate backbone.
* Nitrogenous bases: Attached to each sugar molecule in the backbone are four different nitrogenous bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
* Genetic code: The sequence of these bases along the DNA strand determines the genetic information. For example, a sequence of three bases (a codon) codes for a specific amino acid, which is the building block of proteins.
In summary, the sequence of nitrogenous bases, not the sugar-phosphate backbone, determines the genetic information.
