What is Molecular biology?
'''Molecular biology''' is the study of [[biology]] at a [[Molecule|molecular]] level. The field overlaps with other areas of [[biology]] and [[chemistry]], particularly [[cell biology]], [[genetics]], [[biophysics]] and [[biochemistry]].<ref>Alberts B. Johnson A. Lewis J. Raff M.

Darnell J. 2004. ''Molecular cell biology'', 5th ed. Freeman, NY.</ref> Molecular biology tries to explain the interactions between the various systems of a [[cell]]. It studies the relationship of [[DNA]], [[RNA]] and [[protein biosynthesis|how proteins are made]], and how these interactions are regulated. == Relationship to other specialities == [[Image:Schematic relationship between biochemistry, genetics and molecular biology.svg|thumb|250px|right|''Schematic relationship between biochemistry, genetics and molecular biology'']] 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 substance]]s and vital processes occurring in living [[organism]]s. *''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 [[macromolecule]]s. This includes the chain of events from [[gene]] to [[protein]]: [[DNA replication|replication]], [[transcription (genetics)|transcription]] and [[translation (genetics)|translation]]. Much of the work in molecular biology is [[Quantitative analysis (chemistry)|quantitative]], and recently much work has been done at the interface of molecular biology and computer science in [[bioinformatics]] and [[computational biology]].
