The right side shows the ribosome with an empty A site aligned with the codon 5’UAU 3’.
The next tRNA to occupy the A site on the ribosome will have what anti-codon sequence
( label 5' and 3’)? Keep in mind the wobble pairing rules and make sure your answer is
consistent with the genetic code. Explain your answer.
а.
b. Suppose, just as the ribosome started translating the mRNA, the cell suddenly lost
all of its alanine tRNAs. Using the figure above as a guide, draw and label the state
the ribosome would arrest in.

- Q34. mRNA decay (breakdown) can play an important role in controlling protein abundance. Which of the following scenarios correctly describes a relationship between mRNA decay and protein abundance? A. A decrease in transcription with an increase in the rate of mRNA decay can result in increased protein abundance. B. An increase in transcription with an increase in the rate of mRNA decay can result in no change in protein abundance. C. An increase rate of protein synthesis but failure to form an apoprotein can be explained by a decrease in mRNA decay. D.
