You must try the simulation before answering the questions.
Click the button to simulate the RNA translation process. You can then click on the bases in the mRNA molecule to change them—each base cycles between adenine (A), uracil (U), guanine (G), and cytosine (C)—and click the button again to re-run the simulation and see what your new mRNA produces.

Question
Change the first base in the simulation back to adenine by clicking on the letter three more times. Click on other bases in the sequence and run the simulation to see what peptide is created. How many codons in this sequence can be altered at a single position to result in a prematurely terminated peptide?
A.
B.
C.
D.
E.

Question
Determine whether each of the following statements about the simulation is true or false.
Changing the adenines t the 3’ end of the mRNA will result in a nonfunctional protein because it is critical that every protein possesses a tail of lysine amino acids at the C-terminus.
Changing the guanine in the sixth codon of the original sequence to an adenine will not change the outcome of the simulation.
Every amino acid in a synthesized polypeptide enters the ribosome at the A site.
Changing the uracil in the first codon of the original sequence to a cytosine will not change the outcome of the simulation.
By changing zero, one, or two bases from each of the labeled codons, it is possible to create a tetrapeptide (four amino acids) of all methionines.
