- A gene contains the information necessary to build a specific protein. This information is stored in the sequence of the building blocks of the DNA molecule — and the four bases Adenosine, Cytosine, Guanine, and Thymine. These are abbreviated to A, C, G, and T. To build a protein according to the instructions in the gene, an RNA-copy of the DNA is made and transported for…
