Check All That Apply The disadvantage of using molecular approaches for animal classification is that the information collected is more difficult to quantify than traditional approaches using body plan. Molecular techniques primarily compare the sequences of DNA or RNA to evaluate relatedness. SsU FRNA is a large molecule that contains a lot of genetic information and is used for classification because it is universally found in all organisms. Nucleotides found in a rRNA sequence would include A, T, G, and C. New evidence from molecular techniques suggest that the Annelida and the Arthropoda are not as closely related as traditional approaches would indicate.
