Which description explains the role of the tRNA in the process shown in this model?

• The model reads the message of nucleic acids, or nucleotides, and translates it into proteins, or amino acids.

• The model recognizes when mutations occur and fixes them on the DNA strand.

• The model signals the unzipping of the DNA strand prior to DNA replication.

• The model scans the developing peptide to make sure that the sequence of the amino acids matches the mRNA.
