What type of RNA carries amino acids to the ribosome?

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

Answer: (A)

During translation, amino acids are delivered to the ribosome by transfer RNA. Each tRNA molecule has a specific amino acid attached at its 3' end and an anticodon that pairs with a complementary codon on the mRNA. This pairing ensures the right amino acid is added to the growing polypeptide chain in the order specified by the mRNA sequence. The aminoacyl-tRNA synthetases charge tRNAs with their correct amino acids, making the delivery precise. In contrast, mRNA provides the genetic code for the sequence of amino acids, rRNA forms the ribosome's structural and catalytic core, and snRNA is involved in RNA splicing. So the RNA that carries amino acids to the ribosome is transfer RNA.
