SYSTEMS BIOLOGY Meaning and
Definition
-
Systems biology is an interdisciplinary field of study that focuses on analyzing and understanding complex biological systems as a whole, instead of studying individual components in isolation. It involves the application of various mathematical, computational, and experimental methods to comprehend the behavior, organization, and functioning of biological systems.
At its core, systems biology aims to integrate biological data from multiple levels of organization, ranging from molecular and cellular to tissue, organ, and organismal levels. By incorporating experimental techniques such as genomics, proteomics, metabolomics, and imaging, systems biologists strive to generate large-scale datasets that capture the intricate interplay between different biological components. These datasets are then analyzed using computational and statistical models to uncover emergent properties, patterns, and relationships that were previously unseen.
Furthermore, systems biology employs network-based approaches to capture and represent biological interactions, such as gene regulatory networks and metabolic pathways. The study of these networks aids in understanding how different components work together to perform specific functions and contribute to the overall behavior of the system.
By employing a holistic approach to studying biology, systems biology aims to decipher the underlying principles and rules that govern biological systems, leading to a more comprehensive understanding of life processes. It has applications in diverse areas, including medicine, drug discovery, agriculture, and environmental science, and holds tremendous potential for advancing biological research and solving complex biological problems.
Etymology of SYSTEMS BIOLOGY
The word "systems biology" is derived from two components: "system" and "biology".
The term "system" has its roots in Latin, specifically from the word "systema", meaning an organized or orderly arrangement. It entered English via the Old French word "système", and has been in use since the 17th century in various scientific and technical contexts to refer to a group of interacting or interrelated components working together to achieve a common goal.
"Biology" is also derived from Greek origins. The word comes from the combination of two Greek words, "bios" (meaning life) and "logos" (meaning study or knowledge). When combined, "biology" means the scientific study or knowledge of life and living organisms.
