Every gene consists of several functional components, each involved in a different facet of the process of gene expression (Figure 2-1). Broadly speaking, however, there are two main functional units: the promoter region and the coding region. Gene expression. A gene's DNA is transcribed into mRNA which is, in turn, translated into protein.

Introduction to genetics - Wikipedia
Genes are pieces of DNA that contain information for the synthesis of ribonucleic acids (RNAs) or polypeptides. Genes are inherited as units, with two parents dividing out copies of their genes to their offspring. Humans have two copies of each of their genes, but each egg or sperm cell only gets one of those copies for each gene.
