Gene Function

Gene Function describes how a gene helps to create specific proteins and other components to contribute to an organisms’s growth and development. A single gene contains DNA which is used as a template to create specific proteins. These proteins are involved in cellular functions and, in turn, contribute to the formation of tissues, organs and other physical characteristics. Genes play a critical role in the development of all organisms, from viruses, to plants, to humans. Variations in gene composition can cause genetic diseases such as cystic fibrosis or Huntington’s disease, as well as other inherited traits. The study of gene function has been instrumental in better understanding how organisms function. It has helped to develop treatments for genetic diseases and has also been important in improving crop production, animal breeding and gene therapy.
