[EX Q]: Question: How is the correction of an erroneous amino acid incorporated in the process of translation in the ribosome carried out?
Options: <0> There is no possibility of elimination of an amino acid in the synthesis of proteins. <1> Through the aminoacyl peptidase activity of the ribosome. <2> A dipeptidase removes the wrong amino acid, before proceeding with the synthesis. <3> Thanks to the fact that amino acids are energy-rich molecules. <4> There is a post-translational sequence review system.
[EX A]: pharmacology

[EX Q]: Question: The standard equilibrium constant for a reaction between ideal gases:
