Which RNA carries amino acids to the ribosome?

Which RNA carries amino acids to the ribosome?

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

Answer: (B)

Protein synthesis relies on transfer RNA to deliver amino acids to the ribosome. During translation, the mRNA provides the code, but the actual delivery of the correct amino acid is done by tRNA. Each tRNA is attached to a specific amino acid by aminoacyl-tRNA synthetases, and its anticodon pairs with the corresponding codon on the mRNA to ensure the right amino acid is added in the correct order. The ribosome then catalyzes peptide bond formation to build the protein chain. Remember, mRNA carries the genetic message, rRNA is a structural and catalytic part of the ribosome, and siRNA is involved in gene silencing. Therefore, the RNA that carries amino acids to the ribosome is transfer RNA.
