Question

An understanding of the importance of different factors in a particular interaction is important if confidence in the results is required. Which of the following are not those factors?

(a) Shape

(b) Hydrophobicity

(c) Electrostatics

(d) pH

This question was addressed to me in a national level competition.

I'd like to ask this question from Evaluation of Models & Visualization Methods in section Predicting the Structure of Protein – Biomolecular Interactions of Bioinformatics

Answer 1

The correct choice is (d) pH

Easy explanation: Not that the parameter pH is not related at all but is quite distinctly related to the mentioned factors. Also, pH is relative to the state of the molecule at given instant, other factors being evolutionary relationships and conformational flexibility.
