Question
Inspect the cartoon of a ribosome translating an mRNA below and answer the following questions. Assuming this is a eukaryotic ribosome, which amino acid was brought to the ribosome by the tRNA that has just left the E site? (We want the name of the particular amino add.) Based on your answer for (a), the anticodon on the tRNA that left the E site must be (show polarity): Where will the codon currently in the A site be after the fourth tRNA (the one shown entering the A site above is the third) enters the ribosome? When the next amino acid is added to the peptide chain, the N-terminal amino acid will be in which site of the ribosome (A, P, or E)?Explanation / Answer
a. Met- methionine- initiation codone codes for Met
b. 3'AUG5'
c. one codone down to E- site.
d. E- site- new codone is added to the C terminal on the right side.
