Standard means of distinguishing with high precision especially among prokaryotic species that are new to science.
See, for example, universal tree, which in its modern form is generated via ribosomal RNA sequencing, particularly 16S rRNA genes. See also ribotyping.
Ribosomal RNA sequencing is accomplished in the same manner as DNA sequencing in general. As part of the process, polymerase chain reaction of rRNA genes may be done first to generate sufficient DNA quantities for subsequent sequencing.
