About Human Genetics

Human Genetics is the branch of science concerned with genes, genetic variation and heredity in living organisms and genetic aspects of humans as a species. Genetic information is the information about an individual’s genetic tests and the genetic tests of an individual’s family members, as well as information about the disease or disorder in an individual’s family members. Family medical history is also important because it is often used to determine whether someone has an increased risk of getting a disease, disorder, or condition in the future. Progress in molecular biology has clarified the molecular structure of chromosomes and their constituent genes and the ways in which change in the molecular structure of a gene helps to overcome a disease. The genetic information of the developing human is stored in coded form within molecules of DNA (deoxyribonucleic acid). DNA is composed of a chain like arrangement of smaller molecules known as nucleotides, which forms a code that contains information and it defines the structure of various protein molecules.
