Question

Most domain families only interact with one or two other families, while a few families are extremely versatile in their interactions and are connected to many families.

(a) True

(b) False

I had been asked this question in exam.

Query is from Structural Analyses of Domain Interactions topic in portion Global Approaches for Studying Protein – Protein Interactions of Bioinformatics

Answer 1

The correct answer is:

(a) True

This statement is true because most protein domain families tend to have specific interactions with a limited number of other families, while some domain families, often referred to as "hub" families, have broad versatility and are involved in interactions with many other families. These versatile families play crucial roles in cellular functions and signal transduction.
