Graph-Based Approaches in Bioinformatics

In the field of Bioinformatics, graph-based analysis is essential for comprehending intricate biological systems. The paper emphasizes the different meanings assigned to edges and non-edges in network interactions. After defining key terms from graph theory and bioinformatics, the discussion focuses on the role of Transcriptional Regulatory Networks (TRNs) and Protein-Protein Interaction (PPIs) Networks. The paper examines the application of graph theory in studying various biological systems. Examples include DNA sequence graphs, Signal Transduction Networks, Metabolic and Biochemical Pathways. Additionally, it highlights the use of expert algorithms as implementations to manage uncertainty and incompleteness which are critical in the domain of bioinformatics and molecular biology. Finally, the study addresses the challenges of using graph-based approaches for handling dynamic biological networks. This paper explores the role of graph-based analysis in enhancing our understanding of complex biological systems.
