The figure below shows a ribosome in the process of translating an mRNA with a sequence: 5'...AUGCCGUAUGCUCUUUAA..3'

a) The right side shows the ribosome with an empty A site aligned with the codon 5'UAU3'. 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.

b) Suppose, just as the ribosome started translating the mRNA, the cell suddenly lost all of its alanine tRNAs. Using the figure as a guide, draw and label the state the ribosome would arrest in.
