Summary
Systems biology defines living systems by their complexity, not just data integration. This new discipline uses a five-dimensional framework to understand life's intricate properties and mysteries.
Area of Science:
- Systems biology
- Genomics
- Proteomics
- Computational biology
Background:
- The rapid influx of genomic and proteomic data has spurred the emergence of systems biology.
- A precise definition for systems biology remains elusive, despite widespread initiatives.
- Existing definitions often focus on data integration or network analysis.
Purpose of the Study:
- To propose a precise definition for systems biology.
- To establish systems biology as the study of fundamental properties of living system complexity.
- To introduce a framework for understanding and classifying systems biology research.
Main Methods:
- Dissecting systems complexity into five dimensions: molecular, structural, temporal, abstraction/emergence, and algorithmic.
- Developing a conceptual framework based on these five dimensions.
- Analyzing the scope and goals of current systems biology programs.
Main Results:
- Systems biology is defined as the discipline addressing the fundamental properties of living system complexity.
- A five-dimensional framework (molecular, structural, temporal, abstraction/emergence, algorithmic) is proposed.
- This framework can compare, classify, and complement diverse systems biology programs.
Conclusions:
- The proposed five-dimensional framework offers a structured approach to systems biology.
- Understanding systems complexity is key to unraveling life's mysteries.
- This framework highlights the magnitude of challenges in systems biology research.

01:26Signal and System
A signal x(t) is a set of data or a time function representing a variable of interest. Signals typically convey information about a phenomenon, such as atmospheric temperature, humidity, human voice, television images, a dog's bark, or birdsongs. More generally, a signal can be a function of more than one independent variable. For instance, images depend on horizontal and vertical positions and can be regarded as two-dimensional signals. However, this text will focus on one-dimensional signals...
01:09Levels of Organization
Biological organization is the classification of biological structures, ranging from atoms at the bottom of the hierarchy to the Earth's biosphere. Each level of the hierarchy represents an increase in complexity that builds upon the previous level.Molecules Are Composed of Atoms, and Biomolecules Are Assembled from Molecules:The most basic levels include atoms, molecules, and biomolecules. Atoms, the smallest unit of ordinary matter, are composed of a nucleus and electrons. Molecules comprise...
01:28Global Regulatory Systems
Global regulatory systems in bacteria enable rapid and coordinated responses to environmental changes by integrating sensory inputs with gene expression, ensuring efficient adaptation to fluctuating conditions. Key global regulatory mechanisms include regulons, two-component systems, sigma factors, and secondary messengers.Regulons and Global RegulatorsA regulon is a collection of genes and operons controlled by a common global regulator. These regulators enable bacteria to prioritize resource...
02:55Synthetic Biology
Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

02:02Genomics
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...
01:22Cell Size
Cell sizes vary widely among and within organisms. Bacterial cells range between 1-10 micrometers (μm)and are considerably smaller than most eukaryotic cells. The smallest bacteria are 0.1 μm in diameter—about a thousand times smaller than eukaryotic cells, which typically range from 10-100 μm.Surface AreaCells can take in nutrients and water via diffusion through the plasma membrane itself or through specific channels in the membrane. The area of the membrane surrounding the cells limits the...
