12) In order to attach a particular amino acid to the tRNA molecule for transport, an enzyme---
aminoacyl-tRNA synthetase--- is required along with ATP. The synthetase enzyme has open
binding site for ATP and another for the amino acid, but it is not yet able to attach the tRNA.
What must occur in order for the tRNA to be attached?
A) The ATP must first have to attach to the tRNA.
B) The binding of the first two molecules must cause a 3-D change that opens another binding
site on the enzyme.
C) The ATP must be hydrolyzed to allow the amino acid to bind to the synthetase.
(D))The tRNA molecule must have to alter its shape in order to be able to fit into the active site
with the other two molecules
