First, let's remember that our DNA is found in really nice organized packages called chromosomes. Humans have 23 pair of chromosomes = 46 in total. Each chromosome has a short arm (p=petit) and a long arm (q=comes after p). 
Genes are segments of DNA where each codes for a specific protein.
Genes are found along chromosomes in a predictable location and order. For example, the CFTR gene is found on the long arm of chromosome 7 in all humans.
