RNA is unique for its capability to bridge information from nucleotide polymer (RNA) to amino acid polymer (protein). ... These amino acids are correctly charged onto the adenosine terminal of the tRNA molecule by aaRSs.

AUG is the start codon present on messenger RNAs( mRNA) and has a special tRNA for carrying methionine to pair with it.These tRNAs are called initiator tRNAs.
They carry methionine or formylated methionine to start the process of protein synthesis( translation).
Another unique feature is that it is the only tRNA that can bind to the P site of the ribosome during the process of translation.
Also, it is the only one tRNA that does not bind to the elongation factor in this process.
