Molecular biology / m ə ˈ l ɛ k j ʊ l ər / is a branch of biology that seeks to understand the molecular basis of biological activity in and between cells, including biomolecular synthesis, modification, mechanisms, and interactions.
Cell and molecular biology are related fields of biology that are often combined.

Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional ...
Biologists are able to study life at multiple levels of organization, [1] from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations. [1] [6] Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use.
Cell Biology in "The Biology Project" of University of Arizona. Centre of the Cell online; The Image & Video Library of The American Society for Cell Biology Archived 2011-06-10 at the Wayback Machine, a collection of peer-reviewed still images, video clips and digital books that illustrate the structure, function and biology of the cell.
Cellular microbiology is a discipline that bridges microbiology and cell biology. The term "cellular microbiology" was coined by the authors of the book of the same title published in 1996. [ 1 ] Cooperation and mutual dependency between microbiology and cell biology had been increasing in the years before that, and the emergence of a new ...
Any difference in the concentration of biomolecules between two spaces within a biological system, whether intracellular, extracellular, across a membrane (e.g. between the cytoplasm on one side of the membrane and the external environment on the other), or between different cells or different parts of a tissue or organ system.
Cell signaling is a fundamental property of all cellular life in prokaryotes and eukaryotes. Typically, the signaling process involves three components: the signal, the receptor, and the effector. [citation needed] In biology, signals are mostly chemical in nature, but can also be physical cues such as pressure, voltage, temperature, or light
