why are genes from ribosomal rna (rrna) used to compare genetic sequences between species?

Show more Show less



Ribosomal RNA allows comparative genetics up to the limit of species because its function has essentially stayed consistent throughout the history of life on Earth, but has changed enough across the different species due to mutation to be useful in comparisons of their relative evolutionary timelines. The mutations alter the specific sequences for each species rRNA and these variations allow for analysis and differentiation of organisms at that level.
