The question was asked during an internship interview.

This question is from BAC Vector, M13 and its Derivatives in division Other Vector Systems for E of Genetic Engineering

Answer 1

Correct choice is (c) The most common protein coding genes are gene II or gene VIII

The best I can explain: The filamentous phage is often used as phage display system. The coding sequences are inserted in one of the protein coding genes and the most common protein coding genes are gene III and gene VIII. The insert is expressed along with other protein coat genes.
