GRAPH THEORY APPLICATIONS IN BIOLOGY

*S. Naga Durga and M. Durgadevi and K. Rama devi

ABSTRACT

Mathematics plays a key role in many disciplines of science, primarily as a mathematical modeling tool. A survey of the use of graph theoretical techniques in Biology is presented. In particular, recent work on identifying and modeling the structure of bio-molecular networks is discussed, as well as the application of centrality measures to interaction networks and research on the hierarchical structure of such networks and network motifs. One can think is mathematics has that same important role or even lesser important role in the field of biology and is mathematics and biology could possibly have anything in common. As an effective modeling, analysis and computational tool, graph theory is widely used in biological mathematics to deal with various biology problems. In the field of microbiology, graph can express the molecular structure, where cell, gene or protein can be denoted as a vertex, and the connect element can be regarded as an edge.

Keywords: Mathematical modeling, Biological Networks, Graph, Vertex, Edge.
