A) Highly conserved genes, such as the DNA of mitochondrial DNA, are useful for studying primitive relationships between organisms.
B) The stability of DNA is the basis for studying the evolutionary relatedness of organisms.
C) Regions of DNA where base substitutions accumulate rapidly are useful for studying the phylogeny of closely related organisms.
D) As the DNA mutation rate is constant, DNA analysis provides more accurate information on relatedness of organisms than morphology.
E) Nuclear genes such as ribosomal DNA are constant and so are no use in examining relatedness of organisms.
