oriented relative to each other? - Answer-Alternating amino acid side chains point in
opposite direction

involves the: - Answer-#1 carbon

Archaea adjusts bkiomembrane fluidity by: - Answer-- Having glycerol-tetraether

acids and D-sugars

Which of the following could be used by microbes as final electron acceptors?
a) Oxygen
b) Nitrate
c) Sulfate
d) Two of the above
e) All of the above - Answer-e) All of the above

True or False: For favorable reactions (i.e. exergonic), enzymes reduce the activation
energy for substrate(s) to reach transition states and reduces the free energy released.
- Answer-False

, Which of the following is/are not used to control the tryptophan operon in E. coli during
attenuation? - Answer-Rho-dependent transcriptional terminator

Which type(s) of transposon utilizes a resolves? - Answer-Replicative transposons

Cell-to-cell communication in Gram-negatives as a quorum generally utilizes what
molecule? - Answer-Acylated homoserine lactones

The pentose phosphate pathway provides: - Answer-- NADPH
- 4- and 5-carbon sugars for amino acid and nucleic acid synthesis

The microbe(s) that cannot produce oxygen during photosynthesis is (are): - Answer--
Green sulfur and non-sulfur bacteria
- Purple sulfur and non-sulfur bacteria

Which of the following are step(s) in translation elongation?
a) 30S ribosomal subunit and IF-3 binding
b) Aminoacyl-tRNA binding

False

True or False: DnaK/L and GroEL/ES of E. coli are intense to help cut and fold proteins
using ATP - Answer-False

What is/are characteristic(s) of Archaea? - Answer-- They have 70S ribosomes like
bacteria that are not typically inhibited by antibacterials
- They can have mRNA that are polycistronic

True or False: Pasteurization is not sterilization, but it is a process to reduce microbes
preventing them from spoiling food and beverages - Answer-True

Normally, what is true about photosynthesis?
a) Oxygen donates its electrons, which gets excited by light to initiate electron transport
b) NADPH or NADH donates its electrons to initiate electron transport
c) Both can happen in photosynthesis
d) None of these happens in photosynthesis - Answer-d) None of these happens in
photosynthesis

True or False: A piece of DNA entering a cell is suicidal if it does not have an origin of
replication - Answer-True
