Summary: The structure of cellular networksThe structure of cellular networks
To be able to construct and analyze a cellular network, we need
to clearly define what we identify as a node and what we
represent with an edge.
The nodes and edges have to be at least similar to each other,
e.g. represent the same type of cellular component (protein,
chemical) or the same type of interaction (mass transfer,
regulation).
We can, and often need to, define different types of nodes and
edges.
