Question

Quizplus · Accepted Answer

Phylogenetic stains, such as those used in phylogenetic FISH, hybridize with ribosomal RNA (rRNA). This is because rRNA is highly conserved among organisms and can be used to infer evolutionary relationships. Mitochondrial DNA and nuclear DNA can also be used for phylogenetic analysis, but these stains specifically target rRNA. RNA polymerase is not a target for phylogenetic stains.
