Microbiology with Diseases by Taxonomy ,Fifth Global Edition. What are the three strategies used to identify prokaryotes? A system of numerical taxonomy may be based on similarity matrices or it may be based on the ratio of the bases guanine + cytosine/adenine + thymine (% GC) as a percentage of total DNA bases of the microorganism. 3.1 ) (see also Owen 2004 in Recommended reading list). Numerical taxonomy, which could evaluate all of the characters simultaneously, is one of the popular methods used in the taxonomy of many species since it is more objective than the traditional ones. The organisms are arranged in their respective taxa based on the similarities and differences.
