Why is ribosomal RNA especially useful for the study of phylogenetic relationships? Its function differs in different organisms. It is extremely short. It is highly conserved. It is only found in some species, helping to distinguish them from others.

What feature of the ribosomal RNA (rRNA) gene makes it a good choice for phylogenetic analysis? Group of answer choices eukaryotic organisms have ribosomal RNA, but archaea and bacteria use a different enzyme to make proteins sequence differences correspond to evolutionary distance rRNA breaks down easily so the rate of its decay is associated with evolutionary relationships mutations in the rRNA gene are always lethal, so the genes are identical across biological classifications

Ribosomal RNA is used to compare evolutionary relationships between organisms because It is required for processes that all organisms share, such as protein synthesis. It does not get translated into a polypeptide. It is the easiest to sequence thus several organisms can be sequenced simultaneously. It is more likely to have mutations and thus lead to evolution.
