question 31

Multiple Choice

An mRNA molecule with the sequence 5′-CCG-ACG-3′is being translated at a ribosome. The following charged transfer RNA molecules (with their anticodons shown in the 3′ to 5′ direction) are available. Two of them can correctly match the mRNA so that a dipeptide can form.
Which of the following dipeptides will form from this mRNA?
A) cysteine-alanine
B) proline-threonine
C) glycine-cysteine
D) alanine-alanine
