Which of the following is the best evidence for a three-domain system? - Answer-
Nucleotide sequences in ribosomal RNA vary between all three domains.
A biochemical test, in the microbiology world, is used to determine - Answer-capability
of a microbe to perform a specific enzymatic activity.
Which of the following is NOT based on nucleic-acid hybridization? - Answer-Western
blotting
The phylogenetic classification of bacteria is based on - Answer-rRNA sequences.
Which of the following statements is a reason for NOT classifying viruses in one of the
three domains of life (Bacteria, Archaea, Eukarya) rather than in a fourth separate
domain? - Answer-Viruses are not composed of cells.
, Which of the following provides taxonomic information that includes the information
obtained in the others listed? - Answer-cladogram
