Genes are the instructions stored in the molecule that carries hereditary information, and in most organisms that molecule is DNA. DNA's structure, with long sequences of nucleotides, lets genes be precisely encoded, copied, and transmitted from one generation to the next. Genes are specific regions within DNA that are transcribed into RNA and often guide the production of proteins (or functional RNA molecules). While RNA can serve as genetic material in some viruses, and proteins and lipids play other roles in the cell, DNA is the molecule that houses genes in typical cellular life.
