Cоnsider а hypоtheticаl scenаriо in which each of the following oligopeptides is capable of folding into a stable native state in aqueous solution. When we measure the rates at which each of these oligopeptides folds starting from the denatured (i.e. unfolded) state, we find that three of them appear to fold as single populations, i.e. in these three cases, all copies of the oligopeptide appear to fold at approximately the same rate. In contrast, with the fourth oligopeptide, there appears to be two distinct populations: some copies of the oligopeptide fold rapidly, while other copies fold much more slowly. Given only this information and the sequences shown below, identify the oligopeptide sequence that is most likely to exhibit two distinct folding populations.

Cоnsider а hypоtheticаl glоbulаr protein. Given only what you know about the structures of typical globular proteins and what you know about the structure and properties of the amino acids, which of these mutations is likely to most destabilize the folded (native) state of the protein?
