The person who won the Nobel Prize for discovering that abnormally folded brain proteins that he named prions were the cause of transmissible spongiform encephalopathies was - Stanley Prusiner

In respect to bacterial conjugation, when an F factor becomes integrated into the chromosome of an F+ cell, the cell becomes an Hfr (High frequency recombinant). If this Hfr cell mates (conjugates) with an F- (F minus) recipient, what are the possible outcomes following this mating? (Choose all answers that are correct.) -

Which of the following is not a characteristic of normal cells?

They grow as a monolayer.

They grow as multiple layers.

They undergo a limited number of divisions and then die.

They stick tightly to the surface of glass culture dishes. - They grow as multiple layers.

Shingles is an example of a latent infection that may develop following reactivation decades afer having - chickenpox

True or False

The integration of phage DNA into host DNA occurs in much the same physical mechanism as with transformation, transduction or conjugation. - True

In respect to bacterial conjugation, when an F factor becomes integrated into the chromosome of an F+ cell, the cell becomes an Hfr (High frequency recombinant). If this Hfr cell mates (conjugates) with an F- (F minus) recipient, what are the possible outcomes following this mating? (Choose all answers that are correct.)

A. The donor cell will lose it's F plasmid.

B. The recipient cell will become an F+ cell.

C. The recipient cell will remain an F- (F minus) cell.

D. The donor will remain an Hfr.

E. The recipient will become an Hfr cell.

F. The recipient cell may become a recombinant. - C. The recipient cell will remain an F- (F minus) cell.

Which statement concerning fermentation is FALSE?

Fermentation is a method of producing ATP in the presence of oxygen.
In fermentation, the final electron acceptor is an organic molecule.
NADH is oxidized.
Fermentation is an anaerobic process - Fermentation is a method of producing ATP in the presence of oxygen.

Match the carbon and energy produced/used in aerobic respiration with the microbial metabolic pathway in which it occurs. That is, follow the CARBON and ENERGY. (You may use each answer more than one time.)
