Verified step by step guidance

Understand the role of aminoacyl tRNA synthetase: This enzyme is crucial in the process of translation, where it facilitates the attachment of amino acids to their corresponding tRNA molecules.

Recognize the importance of tRNA: Transfer RNA (tRNA) is responsible for bringing amino acids to the ribosome during protein synthesis. Each tRNA has a specific anticodon that pairs with a codon on the mRNA.

Identify the function of aminoacyl tRNA synthetase: This enzyme catalyzes the esterification of a specific amino acid to its corresponding tRNA, forming an aminoacyl-tRNA complex. This is a key step in ensuring that the correct amino acid is added to the growing polypeptide chain.

Differentiate between the options: The enzyme does not form the tRNA structure, bind tRNA anticodon to mRNA codon, or attach amino acids to the polypeptide chain directly. Its primary function is to attach the correct amino acid to the tRNA.

Conclude with the correct function: Aminoacyl tRNA synthetase ensures the fidelity of protein synthesis by attaching the appropriate amino acid to its corresponding tRNA, which is then used in the ribosome to add the amino acid to the growing polypeptide chain.
