Final answer:
ATP is not involved in the process of tRNA charging carried out by aminoacyl tRNA synthetases.
Step-by-step explanation:
All of the following are involved in the process of tRNA charging except ATP. tRNA charging is the process by which tRNA molecules are linked to their correct amino acids. This process is carried out by a group of enzymes called aminoacyl tRNA synthetases, which attach the amino acid to the tRNA, making it a charged tRNA. ATP is not directly involved in this process, but it is required for the charging of the tRNA.
