if two organisms have similar rRNA sequences, you can conclude that they

evolved from a common acestor

A genus can best be define as

a taxon composed of one or more species and below family

A bacterial species differs from a species of eukaryotic organism in that a bacterial species

is a population of cells with similar characterisstics

Biochemical tests is an identification method to

determine presence of bacterial enzymes

Morphological characteristics is

useful for identifying eukaryotes

Differential staining is most used for

gram staining, acid-fast staining

g) No hybridization: organisms unrelated

The phylogenetic classification are

a) the study of the evolutionary history of organism

The phylogenetic of bacteria is based on

rRNA sequences

Classification of Prokaryotes are

a) a population of cells with similar characteristics

b) culture: grown in lab media

c) clone: population of cell derived from a single cell
