Question
You perform a translation experiment with mRNA and all required molecules in two
identical test tubes. You add limiting amounts of the antibiotic puromycin to test
tube 2 only.
Puromycin is a molecule that has structural similarities to the 3' end of a charged
TRNA. It can enter the ribosome and be incorporated into the growing protein. When
puromycin is incorporated into the polypeptide, it stalls the ribosome and the
polypeptide is released.
You do not know if puromycin recognizes a specific codon or not.
You examine the length of the polypeptide produced in both test tubes.
Which of the following would you find in test tube 2 (has limiting amounts of
puromycin) if puromycin does NOT recognize a specific codon.
O Only 4 types of polypeptides that are each of different lengths
Only 2 types of polypeptides that are each of different lengths
Only a single type of polypeptide
Polypeptides of all sizes, i.e., dipeptides, tripeptides..a polypeptide 90 amino
acids long
