What does tRNA stand for?

• A. Transfer RNA
• B. Transport RNA
• C. Transcription RNA
• D. Telomeric RNA

Answer: (A)

tRNA stands for transfer RNA. In protein synthesis, it acts as the adaptor that brings a specific amino acid to the ribosome and matches it with the corresponding codon on the mRNA via its anticodon, effectively transferring the amino acid to the growing polypeptide chain. The name reflects this transfer function. The other phrases aren’t accurate for this molecule: there isn’t a role called transport RNA or transcription RNA in the ribosome’s workflow, and telomeric RNA relates to chromosome ends, not translation.
