Solution
The correct option is D Aminoacyl synthetase
Amino acid activation refers to the attachment of an amino acid to its transfer RNA (tRNA). It is done by aminoacyl synthetase which catalyzes the covalent joining of the amino acid to tRNA.
So, the correct answer is option 'Aminoacyl synthetase'.
