Genetics is a biological science that involves the study of genes or heredity in living beings, including humans. Although genetics is a biological science, it is highly interdisciplinary in nature as it often collaborates with other life sciences and it is closely linked with the study of information systems. Traditionally, ‘Genetics’ discussed the way the characteristic traits of the organism are inherited or passed on from one generation to the next. Of late the 21st century researchers have extended the study of genetics beyond the inheritance study and extended to study the structure, function, variations, and distribution of genes within the context of the cell, the organism and population. This gives way to emergence of several sub-fields within this field, such as epigenetics and population genetics. Genetics broadly covers the domains of life, plants, animals, microorganism and human.
Molecular biology deals with the biological activity at the molecular level. It is a biological science that overlaps with Genetics and Biochemistry. It generally studies biological activity between the various systems of a cell that includes DNA, RNA, proteins, and their biosynthesis. Until 1960s the researchers studied molecular biology by isolating and manipulating
