DAT 16. Taxonomy Practice Exam
Questions & Answers.
The order of Taxa in order from the general to the specific are? - CORRECT ANSWER Kingdom, Phylum,
Class, Order, Family, Genus, Species
what is the classification system that is used today, based on DNA analysis which more accurately
reflects evolutionary history and the relationships among organisms. - CORRECT ANSWER three domain
systems
what are the Three Domains in the system? - CORRECT ANSWER Bacteria, Archaea, and Eukarya.
of the three domains which contain prokaryotes? - CORRECT ANSWER Bacteria and Archaea.
of the 3 domains which have this particular characteristic (membrane encloses organelles). - CORRECT
ANSWER only Eukaryotes has this characteristic. Bacteria and Archaea do not.
of the 3 domains which have this particular characteristic (Peptidoglycan in the cell wall). - CORRECT
ANSWER only bacteria. Archaea and Eukarya do not have peptidoglycan.
of the 3 domains which have this particular characteristic (RNA polymerase) - CORRECT ANSWER
Bacteria has only one type. Archaea and Eukarya have several kinds.
of the 3 domains which have this particular characteristic (introns which are noncoding regions of
genes). - CORRECT ANSWER introns are absent in bacteria. Introns are only present in some genes in
Archaea. Introns are completely present in Eukarya.
of the 3 domains which have this particular characteristics (antiobiotic sensitivity to streptomycin,
chlorophenicol). - CORRECT ANSWER bacteria is inhibited by these antibiotics. Archaea and Eukarya are
not inhibited by these antibiotics.
,Which of the 3 Domains is being described: All are single-celled prokaryotes with no internal membranes
(no nucleus, mitochondria, or chloroplasts). - CORRECT ANSWER bacteria
Which of the 3 Domains is being described: are Unicellular - CORRECT ANSWER Archaea
Which of the 3 Domains is being described: all organisms have a nucleus and internal organelles -
CORRECT ANSWER eukarya
Which of the 3 Domains is being described: No peptidoglycan in cells - CORRECT ANSWER archaea and
eukarya
Which of the 3 Domains is being described: Includes the four remaining kingdoms: Protista, Fungi,
Plantae, and Animalia - CORRECT ANSWER Eukarya
Which of the 3 Domains is being described: Some are anaerobes (does not requires oxygen); some are
aerobes - CORRECT ANSWER Bacteria
Which of the 3 Domains is being described: Play a vital role in the ecosystem as decomposers that
recycle dead organic matter. - CORRECT ANSWER bacteria
Which of the 3 Domains is being described: Many are pathogens, disease causing. - CORRECT ANSWER
bacteria
Which of the 3 Domains is being described: Play a vital role in genetic engineering. Ex: in the human
intestine, E coli, are used to manufacture human insulin. - CORRECT ANSWER bacteria
Which of the 3 Domains is being described: Contain prokaryotes - CORRECT ANSWER Bacteria and
Archaea
Which of the 3 Domains is being described: Includes extremophiles, organisms that live in extreme
environments like Methanogens, halophiles, and thermophiles - CORRECT ANSWER Archaea
, what type of extremophiles is being described: obtain energy in a unique way by producing methane
from hydrogen. - CORRECT ANSWER methanogen
what type of extremophile is being described: thrive in environments with high salt concentrations like
Utah's Great Salt Lake - CORRECT ANSWER Halophiles
what type of extremophile is being described: Thrive in very high temperatures, like in the hot springs in
Yellowstone Park or in deep-sea hydrothermal vents. - CORRECT ANSWER Thermophiles
Which of the 3 Domains is being described: Introns are present in some genes. - CORRECT ANSWER
Archaea
Which of the 3 Domains is being described: Have no Peptidoglycan - CORRECT ANSWER Archaea and
Eukarya
Which of the 3 Domains is being described: No introns (noncoding regions within the DNA) - CORRECT
ANSWER Bacteria
Which of the 3 Domains is being described: Carry out conjugation, a primitive form of sexual
reproduction where individuals exchange genetic material. - CORRECT ANSWER bacteria
Which of the 3 Domains is being described: Have a thick, rigid cell wall containing a substance known as
peptidoglycan - CORRECT ANSWER bacteria
Which of the 3 Domains is being described: some carry out photosynthesis but others do not. - CORRECT
ANSWER bacteria
Which of the 3 Domains is being described: Viruses are placed in this domain - CORRECT ANSWER
bacteria
What are the 4 kingdoms of the domain Eukarya? - CORRECT ANSWER Protista, Fungi, Plantae, and
Animalia
