Shifting the two bound tRNA from the A and P sites to the E and P sites of the ribosome involves:
a. The movement of the small ribosome subunit down the mRNA chain
b. The degradation of the A site on ribosome
c. The synthesis of the E site on the ribosome
d. The movement of the large subunit relative to the small subunit
e. All of the above
Gene expression can be controlled at the transcriptional level by:
a. Chromatin Structure
b. Activators/repressors
c.assembly of the transcription initiation complex
d.all of the above
Intracellular signaling pathways are awesome! What is the one thing they can NOT do?
a. relay the signal, to spread it through the cell
b. integrate the signal from more than one cellular pathway
c. nothing, they can communicate any cellular need
d. Amplify the signal received, making the signal stronger
e. distribute the signal to more than one effector protein
