Question: Using a probe, you want to determine if a 200 bp CDS exists in the genome of a prokaryotic organism whose genome has not been sequenced. You know the sequence of the CDS you are trying to detect because this CDS exists in E. coli whose genome is sequenced, and because you think that the prokaryotic organism under study might be evolutionarily related to E. coli, the prokaryote might have the same gene.
