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.

Step 1
This means that it undergoes very few mutations, and any mutations that do occur are typically fixed by the cell. This high level of conservation allows scientists to trace evolutionary relationships between different species based on similarities and differences Show more…

What makes ribosomal RNA useful as a molecular clock? What makes ribosomal RNA useful as a molecular clock? A large portion of the DNA ring is not vital to structure or function, allowing it to accumulate neutral mutations. Its rate of mutation increases over time as organisms continue to evolve and differentiate from each other. A slow mutation rate makes it useful for determining evolutionary relationships between ancient species. It is only found in select organisms, making it easier to compare relationships between species that have it. A molecule that can be used as a molecular clock has a neutral mutation rate of one mutation per 20 million years. A molecule that can be used as molecules found in these two species differ by a total of six mutations? 60 million years.
