Which RNA transports amino acids to the ribosome?

Which RNA transports amino acids to the ribosome?

• A. mRNA
• B. rRNA
• C. tRNA
• D. snRNA

Answer: (C)

During translation, tRNA delivers the correct amino acids to the ribosome. Each tRNA carries a specific amino acid and has an anticodon that pairs with a complementary codon on the mRNA, ensuring the amino acids are added in the right order. The amino acid is attached to the tRNA by aminoacyl-tRNA synthetases, using ATP energy. At the ribosome, the tRNA brings its amino acid into place at the A site, the amino acid is transferred to the growing polypeptide, and the tRNA is released to be reused. In contrast, mRNA carries the genetic code, rRNA forms the ribosome and helps catalysis, and snRNA participates in RNA splicing. So, the RNA that transports amino acids to the ribosome is tRNA.
