Nucleotids. Every 3 nucleotids form a codon, several codons give the instructions for assembling an aminoacid, several aminoacids form a protein and several proteins give characteristics or have a special function.

DNA is already the genetic code, there is nothing more in it that codes information. However, DNA is comprised of nucleotides, a set of three which forms a "codon", that together represents the inofrmation, much as bits encode information in a computer.
We cannot, however, say that "nucleotides" code genetic information because alone they are meaningless (1s and 0s alone mean nothing in computer science). DNA is the basic structure that holds genetic information.
This is accomplished during protein synthesis. All functions in a cell depend on proteins; what DNA does is determine which and how much proteins are created. DNA is transcribed to mRNA, then the RNA is "unzipped". Through the process, the exposed codons are used to string together a variety of amino acids, which ultimately form a protein.
How this is specifically done and how the process is controlled is best examined in a biology course.

In DNA, it's the sequence of the nitrogen bases that makes the difference. If the nitrogen bases are AACGTATTGCGTA.... this directs the building of a different protein than AAGCAATTGCGTA.
