C) nuclear DNA.
D) RNA polymerase.

Question

Quizplus · Accepted Answer

Phylogenetic stains, such as those used in FISH, typically target ribosomal RNA (rRNA) sequences, which are generally present in multiple copies per cell and have high sequence conservation within a given taxonomic group. This allows for specific detection and visualization of particular groups of microorganisms or other organisms based on their rRNA sequences. Mitochondrial DNA and nuclear DNA can also be targeted with specific stains, but this is typically done for different purposes than phylogenetic analysis. RNA polymerase is not typically targeted with phylogenetic stains.
