DNA is like our own personal blueprint filled with all the instructions needed to make a functioning body. DNA is contained in the "brain" of the cell, called the nucleus, and is made up nucleotides, which is a chemical compound consisting of a base, sugar, and phosphate. Bases are similar to letters of the English alphabet. Only instead of 26 letters, there are only four: adenine(A), guanine(G), cytosine(C), and thymine(T). These four "letters" when combined in different sequences make up our genetic code.
Each gene carries a complete set of instructions for a unique (or multiple) protein(s) that will perform a specific function(s) in our body. Genes can interact with other genes to produce new proteins and proteins can interact with other proteins to facilitate different functions in our body.
