Verified step by step guidance

Begin by understanding the role of tRNA in protein synthesis. tRNA molecules are responsible for bringing amino acids to the ribosome, where proteins are synthesized.

Recognize that each tRNA molecule must be linked to its corresponding amino acid before it can participate in protein synthesis. This process is known as 'charging' the tRNA.

Identify the enzyme responsible for this 'charging' process. Aminoacyl-tRNA synthetases are the enzymes that catalyze the attachment of amino acids to their corresponding tRNA molecules.

Understand the specificity of aminoacyl-tRNA synthetases. Each enzyme is specific to one amino acid and its corresponding tRNA, ensuring the correct amino acid is attached to the correct tRNA.

Consider the importance of this process in the fidelity of protein synthesis. Accurate attachment of amino acids to tRNA is crucial for translating the genetic code into the correct sequence of amino acids in a protein.
