Final answer:
An ester bond is the type of bond that connects tRNA with its amino acid. This occurs during the charging of tRNA where an aminoacyl-tRNA synthetase enzyme catalyzes the formation of this bond.
Step-by-step explanation:
The type of bond that connects tRNA with its amino acid (AA) is the ester bond. In the process of tRNA charging, an aminoacyl-tRNA synthetase catalyzes the attachment of an amino acid to its corresponding tRNA. The amino acid is linked to the 3' end of the tRNA via an ester bond between the carboxyl group of the amino acid and the hydroxyl group of the ribose in the tRNA's adenosine residue. This forms an aminoacyl-tRNA complex that is ready for protein synthesis during translation in the ribosome.
