9. consider the need for accuracy in the flow of information from dna to rna to functional protein molecules. what are the different levels of stringency in replication, transcription and translation? what kinds of mechanism improve the accuracy of these processes?

How is ribosomal rna useful as a molecular clock? a. a large portion of the dna ring is not vital to structure or function, allowing it to accumulate neutral mutations. b. its rate of mutation increases over time as organisms continue to evolve and differentiate from each other. c. a slow mutation rate makes it useful for determining evolutionary relationships between ancient species. d. it is only found in select organisms, making it easier to compare relationships between species that have it.
