question 40

Multiple Choice

A part of an mRNA molecule with the following sequence is being read by a ribosome: 5′-CCG-ACG-3′ (mRNA) . 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.
$$\begin{array} { | c | c | } \hline \text { tRNA Anticodon } & \text { Amino Acid } \\\hline \text { GGC } & \text { Proline } \\\text { CGU } & \text { Alanine } \\\text { UGC } & \text { Threonine } \\\text { CCG } & \text { Glycine } \\\text { ACG } & \text { Cysteine } \\\text { CGG } & \text { Alanine } \\\hline\end{array}$$
