Question

Interactions between proteins can be predicted computationally by looking for sets of genes that occur as a _______

(a) single gene in at least one genome

(b) multiple genes in at least one genome

(c) multiple genes in various genomes

(d) single gene in various genomes

I had been asked this question in an interview for internship.

Asked question is from The Use of Gene Order & Phylogeny to Predict Protein topic in portion Global Approaches for Studying Protein – Protein Interactions of Bioinformatics

Answer 1

Correct option is (a) single gene in at least one genome

The explanation is: Interactions between proteins can be predicted computationally by looking for sets of genes that occur as a single gene in at least one genome. Or it can be done by looking for prokaryotic genes that have conserved adjacent gene order across several genomes.
