You investigated the cytoskeleton and found that all three elements, including the one you suspected, are completely normal. You then decide to look at the motor proteins to see if the cause of the abnormality might lie with one of them. Which one of the following would be your hypothesis?

a. The melanophores in these tadpoles have partially functional or nonfunctional kinesin that would normally transport organelles along microfilaments to the center of the cell.
b. The melanophores in these tadpoles have partially functional or nonfunctional dynein that would normally transport organelles along microtubules to the center of the cell.
c. The melanophores in these tadpoles have partially functional or nonfunctional dynein that would normally transport organelles along microfilaments to the center of the cell.
d. The melanophores in these tadpoles have partially functional or nonfunctional kinesin that would normally transport organelles along microtubules to the center of the cell.
e. The melanophores in these tadpoles have partially functional or nonfunctional myosin that would normally transport organelles along microfilaments to the center of the cell.


Ans: b. The melanophores in these tadpoles have partially functional or nonfunctional dynein that would normally transport organelles along microtubules to the center of the cell.

The antibiotic rifamycin is selectively toxic in blocking protein synthesis in Mycobacterium tuberculosis because

A. the antibiotic binds to the mRNA once synthesized, preventing it from participating in the initiation complex with the ribosome. B. it binds preferentially to bacterial RNA polymerase rather than the eukaryotic protein, effectively halting transcription in the pathogen but not the host. C. bacterial ribosomes are 70s whereas host ribosome are 80s, thus the antibiotic binds to the M. tuberculosis ribosome but does not bind to the eukaryotic machinery. D. the drug binds to the initiator tRNA, preventing the formation of the protein synthesis initiation complex in the bacterial cell.
