Molecular Biology: Branch of biology that deals with the molecular basis of biological activity
Molecular biology is the study of biology at a molecular level.
The field overlaps with other areas of biology and chemistry, particularly cell biology, genetics, biophysics and biochemistry.
Molecular biology tries to explain the interactions between the various systems of a cell. It studies the relationship of DNA, RNA and how proteins are made, and how these interactions are regulated.
Relationship to other specialities
Researchers in molecular biology use specific techniques that are typical for molecular biology, but they combine these with techniques and ideas from genetics and biochemistry. This diagram shows one possible view of the relationship between the fields:
- Biochemistry is the study of the chemical substances and vital processes occurring in living organisms.
- Genetics is the study of inheritance: the effect of genetic differences on organisms.
- Molecular biology includes the study of the structure and function of all carbon-based macromolecules. This includes the chain of events from gene to protein: replication, transcription and translation. Much of the work in molecular biology is quantitative, and recently much work has been done at the interface of molecular biology and computer science in bioinformatics and computational biology. As of the early 2000s, the study of the genome has been amongst the most prominent sub-field of molecular biology.
- Cytology, which includes the appearance of cells and cell structures, microscopy, and the use of stains and tags to help distinguish organelles and processes.
