Molecular genetics
Molecular genetics builds upon the base of classical genetics but focuses on the structure and function of genes at a molecular level.Molecular genetics employs the methods of both classical genetics and molecular biology. It is so-called to differentiate it from other sub fields of genetics such as ecological genetics and population genetics. An significant area within molecular genetics is the use of molecular information to determine the patterns of descent, and therefore the correct scientific classification of organisms: this is called molecular systematic.
The study of inherited features not strictly associated with changes in the DNA sequence is called epigenetic.Some take the view that life can be defined, in molecular terms, as the set of strategies which RNA polynucleotide have used and continue to use to achieve themselves. This definition grows out of work on the origin of life, specifically the RNA world hypothesis.
