Question

Which of the following is untrue about specialized programs for loop modeling?

(a) PETRA is a web server that models loops using the database approach

(b) FREAD is a web server that models loops using the database approach

(c) CODA is a web server that uses a consensus method based on the prediction results from FREAD and PETRA

(d) For loops of three to eight residues, CODA uses consensus conformation of both methods

The question was asked during a job interview.

I would like to ask this question from Ab Initio Protein Structural Prediction & Homology Modeling in portion Protein Tertiary Structure Prediction of Bioinformatics

Answer 1

Right answer is (a) PETRA is a web server that models loops using the database approach

To explain I would say: PETRA is a web server that uses the ab initio method to model loops. For nine to thirty residues, CODA uses FREAD prediction only.
