Biological network
Method of representing systems / From Wikipedia, the free encyclopedia
A biological network is a method of representing systems as complex sets of binary interactions or relations between various biological entities.[1] In general, networks or graphs are used to capture relationships between entities or objects.[1] A typical graphing representation consists of a set of nodes connected by edges.

The path from node #1 to node #3 is highlighted in red.](http://upload.wikimedia.org/wikipedia/commons/thumb/f/fa/NetworkGraph.png/640px-NetworkGraph.png)
