TESTED QUESTIONS WITH CORRECT
ANSWERS | BRAND NEW!
What proportion of E Coli's genome would be predicted to have
"unknown function"? - ✔✔✔ Correct Answer > 30%
Which of the following about transposons is true? - ✔✔✔ Correct
Answer > They can be carried between cells by conjugation,
transformation, and transduction. Transposons insert randomly
at target sites. Transposition occurs infrequently
Who coined the term "plaque"? - ✔✔✔ Correct Answer > Felix
D'Heurelle
True or False - All viruses are composed of nucleic acid and
protein - ✔✔✔ Correct Answer > True
All of the following compounds can be found in the bacterium
Staphylococcus... - ✔✔✔ Correct Answer > Peptidoglycan, FtsZ,
Bactoprenol (this is a lipid carrier in bacteria), and a Li[id Bilayer
,Page 2 of 102
MreB - ✔✔✔ Correct Answer > If you don't have this you will be
spherical. This makes you a coccoid cell. So MreB is not found in
Staphylococcus
Where would you classify Nanoarchaeum? - ✔✔✔ Correct Answer >
DPANN
During cell wall synthesis in bacteria, when does the
pentapeptide become a tetrapeptide? - ✔✔✔ Correct Answer > When
transpeptidation occurs
True or False - Archaea have a similar RNA polymerase to one of
those in eukaryotes - ✔✔✔ Correct Answer > True
All of these are advantages of being naturally competent except
for... - ✔✔✔ Correct Answer > Obtaining an auxotrophic phenotype
Which of the following is false of generalized transduction? - ✔✔✔
Correct Answer > Some phage DNA in each transducing particle
What will be responsible for replicative transposition - ✔✔✔ Correct
Answer > Resolvase

If you care about high quality gene sequences more than you
care about high throughput, which technology might you choose?
- ✔✔✔ Correct Answer > Sanger is a bit dated but it is still the one we
reach for because it is has very low error rates
If you already have illumine sequences for your genome and your
genome still has gaps, how might you collect long reads to help
bridge the gaps, without primer walking? - ✔✔✔ Correct Answer >
PacBio and Nanopores would work
In involving a streptomycin-sensitive wild type Hfr donor and an
F- recipient that uses a streptomycin resistant leucine auxotroph
(leu-) an appropriate selection for leu+ recombinants would be...
- ✔✔✔ Correct Answer > Defined medium lacking leucine but with
streptomycin
Not very many proteins in the eukaryotic cytoplasmic membrane.
Where did they go? - ✔✔✔ Correct Answer > They are still in the
membrane and they are still busy, but most of the proteins went
to the mitochondrial membrane in eukaryotes.
Cellulose and Chitin - ✔✔✔ Correct Answer > Use specific b-1,4-
glycosidic bonds between sugars provides strength and rigidity.
In algae

Fungi - Cell Wall - ✔✔✔ Correct Answer > You have a NAG in chitin for
cell walls in fungi. The cell wall is all NAGs
Cytoskeleton Function - ✔✔✔ Correct Answer > Involved in
intracellular trafficking, motion, and cell division can be observed
via fluorescent microscopy
Axoneme Structure - ✔✔✔ Correct Answer > Nine pairs of micro
tubules and two more single microtubules in the middle (9 + 2
array)
A new halophile in the dead sea was found. What will its cell wall
look like? - ✔✔✔ Correct Answer > It is an archaea so something with
NAG and NAT
What is the correct match for Tubulin? - ✔✔✔ Correct Answer > FtsZ
What is the correct match for Actin? - ✔✔✔ Correct Answer > MreB
What is the correct match for Plasmids? - ✔✔✔ Correct Answer > ParM
What is the correct match for Cellulose? - ✔✔✔ Correct Answer >
Algae
