What function does tRNA perform in protein synthesis?

• A. It carries genetic information
• B. It carries amino acids
• C. It makes up part of the ribosome
• D. It helps in DNA replication

Answer: (B)

tRNA, or transfer RNA, plays a crucial role in protein synthesis by serving as the adapter molecule that carries amino acids to the ribosome. During translation, the ribosome reads the sequence of mRNA (messenger RNA) codons, which specify the order in which amino acids should be linked together to form a protein. Each tRNA molecule has a specific anticodon that pairs with the corresponding codon on the mRNA, ensuring that the correct amino acid is incorporated into the growing polypeptide chain. As such, the primary function of tRNA is to carry amino acids, facilitating the translation process and ultimately leading to the synthesis of proteins based on the genetic code.
