Final answer:
There is at least one aminoacyl-tRNA synthetase for each amino acid, not multiple, which is crucial for tRNA charging during protein synthesis.
Step-by-step explanation:
The statement is false; there does not exist multiple aminoacyl-tRNA synthetases for each amino acid. Rather, there is at least one aminoacyl-tRNA synthetase for each of the 20 amino acids. These crucial enzymes bind to and hydrolyze ATP to facilitate the attachment of an amino acid to its corresponding tRNA, a process known as tRNA charging. The activated amino acid forms a high-energy bond with adenosine monophosphate (AMP), and subsequently, this aminoacylated tRNA is used during protein synthesis.
