Which molecule brings amino acids to the ribosome during translation?

Explanation:
In translation, the amino acids are delivered to the ribosome by adaptor molecules called transfer RNA, or tRNA. Each tRNA carries a specific amino acid and has an anticodon that pairs with a corresponding codon on the mRNA inside the ribosome. This matching ensures the amino acids are added in the exact order dictated by the mRNA sequence, forming the growing polypeptide. The ribosome then catalyzes peptide bond formation between adjacent amino acids. Other molecules have different roles: mRNA provides the genetic code, rRNA forms and helps the ribosome function, and siRNA is involved in gene silencing rather than translation. So the molecule that brings amino acids to the ribosome is tRNA.
