Detailed explanation-1: -tRNAs (transfer RNAs) carry amino acids to the ribosome. They act as “bridges, ” matching a codon in an mRNA with the amino acid it codes for.

Detailed explanation-2: -tRNA carries the amino acids from the amino acid pool to mRNA during protein synthesis.

Detailed explanation-3: -Each tRNA has its corresponding amino acid attached to its end. When a tRNA recognizes and binds to its corresponding codon in the ribosome, the tRNA transfers the appropriate amino acid to the end of the growing amino acid chain.

Detailed explanation-4: -tRNA molecules bind to the ribosome in a solvent-accessible channel at the subunit interface. Three binding sites for tRNA, called the aminoacyl site (A site), peptidyl site (P site), and exit site (E site), have been identified on both the large and small subunit (Fig.
