-Phenotypic differences can be due to only a few gene products.
Why can DNA sequences be viewed as evolutionary chronometers? - answer Accumulations of
random mutations provide a relative measure of time elapsed since organisms diverged from a

-Ribosomes perform crucial and functionally constant tasks.
-Ribosomal genes are not commonly horizontally transferred.
Why are sequence comparisons of the DNA coding for ribosomal RNA (rRNA) so useful in
