Welcome to the Molecular and cellular biology portal. Molecular biology is the study of biology at the molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Cell biology studies the properties of cells including their physiological properties, their structure, the organelles they contain, interactions with their environment, their life cycle, division and death. Molecular and cellular biology are interrelated, since most of the properties and functions of a cell can be described at the molecular level.
Molecular and cellular biology encompass many biological fields including: biotechnology, developmental biology, physiology, genetics and microbiology.
