What is the function of Transfer RNA (tRNA)?

Transfer RNA (tRNA) plays a crucial role in the process of translation, which is the step in protein synthesis where the genetic code is translated into a specific sequence of amino acids to form a protein. The primary function of tRNA is to bring amino acids to the ribosome, the cellular machinery responsible for assembling proteins.

Each tRNA molecule is associated with a specific amino acid and has a corresponding anticodon that recognizes and pairs with the codons on the messenger RNA (mRNA) strand. During translation, tRNA molecules transport the appropriate amino acids to the ribosome as it reads the mRNA sequence. This ensures that amino acids are added in the correct order to form a polypeptide chain, which ultimately folds into a functional protein.

The other options describe different processes or components of protein synthesis but do not accurately represent the specific function of tRNA. While tRNA does participate indirectly in the formation of proteins, its fundamental and defining role is the transfer of amino acids to the ribosome, making option B the correct choice.
