A group of researchers isolate 'Protein X' from the wall of a human stomach with the intent of learning how to synthesize stomach tissue in the lab. Subsequently, they determine the exact sequence of amino acids of the protein in its unfolded state, and create a functional mRNA template to translate Protein X in vitro. They manage to translate an exact copy of the polypeptide chain in the lab, but then realize that it takes several days for the protein to fold into its final tertiary structure. In vivo, they observe that several thousand copies of Protein X are folded from polypeptide chains every minute. What is NOT a plausible explanation for this difference in folding times?

The in vitro study lacks a key enzyme The temperature in vitro is too low The in vitro study lacks a key tRNA molecule The pH in vitro is too high
