Question

In protein domain family interaction map, the physical contacts of the domains in different families are represented by the lines between the nodes.

(a) True

(b) False

I have been asked this question in a national level competition.

Question is taken from Structural Analyses of Domain Interactions topic in chapter Global Approaches for Studying Protein – Protein Interactions of Bioinformatics

Answer 1

Correct answer is (a) True

For explanation: Each node in this graph represents a protein domain family. There are a few families that are hubs in the network: these are large families that are functionally versatile, such as Rossmann domains indicated by an ‘R’ here. Most families engage in only one or two types of interactions.
