Here's a breakdown:
* DNA is made up of nucleotides. Each nucleotide consists of a sugar (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
* The order of these bases along the DNA molecule forms a code. Think of it like a language with only four letters.
* Genes are segments of DNA that contain the instructions for building specific proteins or other molecules.
* The sequence of bases within a gene determines the sequence of amino acids in the protein it codes for.
* This sequence of amino acids ultimately dictates the protein's structure and function.
So, the order of the bases (A, G, C, T) in DNA determines the specific instructions for building and maintaining an organism.
