CAG-TTG
GUC-AAC

Which description explains the role of the tRNA in the proces shown in this model?
The model reads the message of nucleic acids, or nucleotides, and tranlates it into proteins, or amino acids
The model recognizes when mutations occur nad fixes them on the DNA strand
The model signals the unzipping of the DNA strand prior to DNA replication
The modle scans the developing peptide to make sure that the sequence of the amino acids matches the mRNA
