1 A gene is a small section of DNA that contains the instructions for a specific molecule, usually a protein. 2  The purpose of genes is to store information. 3  Each gene contains the information required to build specific proteins needed in an organism.enes are small sections of DNA within the genome that code for proteins. They contain the instructions for our individual characteristics â like eye and hair colour.
THE LETTERS ARE A, C, G, T. The âHuman Genomeâ is the genetic code - the entire list of three billion letters - required to create a human being. The instructions are encoded in DNA. The four letters in the DNA alphabet â A, C, G, T - carry the instructions to make all living organisms. The meaning of the code lies in the sequence of the letters. All the instructions needed to make a human being are written in just these four letters.
