21

Similarities based on ribosomal RNA living organisms are classified into three domains: bacteria, archaea, Eukarya

Three domain system

22

Placing organisms in groups of related species. It is the systematic grouping of organisms into categories of evolutionary or structural relationships between them based on similarities

Classification

23

Matching characteristics of unknown organism to list of known organism

Identification

24

Population of viruses with similar characteristics that occupies a particular ecological niche

Viral species

Group of bacteria derived from a single cell
Pure culture

Clone

26

Nonidentical clone cells identified by numbers, letters, or names

Strain

27

Closely related strains

Bacterial species

28

Population of cells with similar characteristics

Prokaryotic species

29
