The prompt asks us to consider when gene expression is considered 'complete.'
First, note that the provided data shows the correct answer as: 'The protein is active, correctly folded, and functional.' However, no list of answer options was supplied to evaluate alongside this claim.

Protein disulfide isomerase (PDI) is a protein folding enzyme that catalyzes disulfide–sulfhydryl exchange reactions. Ribonuclease is an enzyme with two β‑sheets, three α‑helices, and four disulfide bridges critical to the stability of its structure. PDI rapidly converts inactive, scrambled ribonuclease to enzymatically active ribonuclease. This process is driven by the decrease in free energy as the scrambled conformations are converted into the stable, active conformation of the enzyme. In contrast, PDI rapidly inactivates insulin, a protein that forms an hexamer of alpha and beta subunits. What does PDI's effect on insulin imply about the structure of insulin?
The Anfinsen experiment we discussed in our meetings showed that protein folding is encoded in the primary structure of a protein. Anfinsen did his experiment at a concentration of 1mg/mL. Choose from the answers below the one you believe represents best what would have ahppened if he used instead the physiological concentration of ribonuclease (~100mg/mL).
Fill in the boxes and the titles of the figure shown above
The role of betamercaptoethanol and urea in Anfinsen's experiment is respectively
