Final answer:
tRNA makes individual binding sites for all amino acids through its specific structure and interactions with other molecules during translation.
Step-by-step explanation:
tRNA (transfer RNA) makes individual binding sites for all amino acids through its specific structure and interactions with other molecules during translation. Each tRNA molecule has a three-nucleotide sequence called an anticodon that is complementary to a specific mRNA codon. The anticodon region of the tRNA binds to the complementary mRNA codon, ensuring that the correct amino acid is inserted into the growing protein chain. Additionally, all tRNAs have a site at the 3'-terminal where the specific amino acid attaches through a process called tRNA charging
