Genetics is the study of genes, which are the basic units of inheritance that contain the blueprint for life, from determining the way that organisms look to every physiological process that occurs within them. Advances in genetics have come a long way since the discovery of the double helix of DNA in 1953. Scientists can now sequence the entire genetic code of thousands of people on a large scale to pinpoint genes that are associated with specific diseases and flag them as targets for drug development. Likewise, enzymes from bacteria can be used to modify genes for a plethora of purposes, including healthcare and farming.
