A) Translocation
B) Amino acid activation
C) Peptidyl-transferase reaction
D) Aminoacyl tRNA binding to active ribosomal site
Correct Answer: D
Solution :
[d] During the activation of amino acids, in the presence of \[M{{g}^{2+}}\] and ATP an amino acid gets attached to a specific enzyme aminoacyl t-RNA synthetase. Pyrophosphate is released which breaks up to release energy. During translocation, in the presence of the enzyme translocase and energy from GTP the ribosome moves in such a way that the peptidyl bearing t-RNA of A - site comes to lie; on the P-site, exposing a new codon at A site. In the peptidyl transferase reaction energy is provided by GTP.You need to login to perform this action.
