A part of an mrna molecule with the following sequence is being read by a ribosome: 5'-ggc-ugc-3' (mrna). The charged transfer rna molecules shown in the figure below (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: trna anticodon amino acid ggc proline cgu alanine ugc threonine ccg glycine acg cysteine cgg alanine which of the following dipeptides will be formed?.
