Molecular genetics is the study of macromolecules that have a role in biological heredity. Genetics is the study of heredity and genes in particular. Individual genes or sets of genes are implicated in health and sickness, according to genetic research. Genetic engineering has been used in medicine to mass-produce insulin, human growth hormones, follistim, human albumin, monoclonal antibodies, antihemophilic factors, vaccinations, and a variety of other medicines, as well as to detect and cure inherited human diseases. Organisms are genetically altered in study to learn more about the activities of certain genes.
