A gene is a region of DNA that controls a hereditary characteristic. Genes contain proteins necessary to build an organism. A gene carries biological information, which is copied and transmitted from each cell to its entire offspring. The estimate for the number of genes in humans has decreased as our knowledge has increased. As of 2001, humans are thought to have between 30,000 and 40,000 genes.
